Insight. Implementation. Integration.

AI, or artificial intelligence, is transforming the products we build and the way we do business. It also presents new challenges for those who need to build AI into their systems. Creating an “AI-driven” system requires more than developing intelligent algorithms. It also requires:

• Insights from domain experts to generate the tests, models, and scenarios required to build confidence in the overall system
• Implementation details including  data preparation, compute-platform selection, modeling and simulation, and automatic code generation
• Integration into the final engineered system

Mike Agostini demonstrates how engineers and scientists are using MATLAB^® and Simulink^® to successfully design and incorporate AI into the next generation of smart, connected systems.

The exploration of unknown environments can be the fundamental problem for mobile robots, as it involves all the basic capabilities of such systems (e.g., perception, planning, localization, and navigation). From a practical viewpoint, exploration is a central task in many applications, such as planetary missions, intervention in hostile areas, and automatic map building.

This presentation focuses on technique known as frontier-based exploration. The rationale of this approach is that the robot must move towards the boundary (the frontier) between safe explored areas and unknown territory to maximize the information gain coming from new perceptions. The talk discusses how to explore indoor spaces in the absence of predefined map, how to navigate the space while avoiding static obstacles, and how to implement the exploration and navigation module in ROS in MATLAB^® and simulate the virtual robot, Husky, in ROS gazebo using Robotics System Toolbox™.

System engineering and model-based system engineering can mean different things to different groups, but most definitions share a common set of concepts, including starting from a set of system-level requirements which are used to drive a system decomposition and requirements allocation process. Then trade-off studies are performed on system architecture alternatives to produce a candidate architecture from which the design is developed and then simulated to verify that the requirements are met.

This presentation shows how MathWorks tools can support this workflow by allowing users to: 

• Capture, view, analyze, and manage requirements
• Develop a system architecture model from the requirements, existing Simulink^® models, ICDs, and externally created architectures or combinations of the above
• Examine the system architecture model using different views for different concerns
• Allocate (link) requirements to architectural components and perform coverage and change impact analysis
• Perform trade studies to compare, assess, or optimize the system architecture
• Design components specified in the system architecture model
• Simulate the system composition to verify system-level behavior

Ather Energy has set out to make a change in the way people perceive electric vehicles. Everyone knows that electric transport is the future, but lack of good products in that space in our country is generally hindering faster adoption of electric vehicle technology. A good product has multiple dimensions that need to be met across performance, user experience, and customer service. The Ather 450, along with their charging infrastructure Point, is the first product out of their factory that looks to meet these dimensions.

The scooter, along with charging infrastructure, creates a complex ecosystem of devices where the interaction between these need to be handled well to optimize performance. The company knew the complexity of the system well enough early on, and for them, it was an easy decision to use MathWorks products. The physical model of the system and the algorithm developed went a long way in helping Ather Energy understand and optimize the performance faster.

Battery management systems (BMS) ensure maximum performance, safe operation, and optimal lifespan of battery pack energy storage systems under diverse charge-discharge and environmental conditions. With Simulink^®, engineers can use simulations to model feedback and supervisory control algorithms that monitor cell voltage and temperature, estimate state-of-charge (SOC) and state-of-health (SOH) across the pack, control charging and discharging rates, balance SOC across the battery cells, and isolate the battery from source and load when necessary. Starting from early design tradeoffs to hardware-in-the-loop (HIL) testing of BMS hardware, Simulink can help engineers perform desktop simulations to ensure the BMS performs as intended under all desired operating conditions and meets design durability requirements. In this talk, you’ll learn how Simulink helps engineers from electrical, thermal, and software backgrounds collaborate throughout the development cycle of BMS algorithms.

Model-based engineering is widely used in industries to build system architectures and engineering applications to enable virtual analysis and qualifications. Within Schindler, physics-based generic system models are developed that serve as the basis for model-based validation, worst-case development to fit to purpose development, and Executable Elevator Body of Knowledge. The model captures the dynamics of the mechanical components (rope, buffer, and overspeed governor) that are driven from electrical components (motor). The motor is controlled by the behaviour model of the main elevator control. Custom Simscape™ blocks are used to accurately model the physics of mechanical components. The elevator controller, drive, and logical components are modelled using Simulink^® and m scripts.

The model development cycle follows the SCRUM methodology. In a sprint of four weeks, the development focus is to improve the accuracy of physical models as well as include additional features and variants of the main controller. This generic model, which involves the various configurations in terms of elevator control components, mechanical components, and onsite installation (number of floor levels), needs to be verified prior to the sprint release. The challenge is to automate verification tests of models, which involves time-variant physical signals.

An automated test framework called Model’s Automated Test Harnesses (MATHS) is developed using Simulink Test™ to perform system-level tests and model-in-the-loop (MIL) tests for subsystem components. Simulink Test provides a good platform to create test harnesses and write corresponding test cases. With new developments, the interfaces and, to some extent, logics of the models change. Therefore, it becomes necessary to create a framework which allows the maximum reuse of the test harnesses and minimum rework on defining test cases.

With Model-Based Design, informal textual requirements can be modeled and simulated to verify behavior earlier, and then be automatically generated into code for an embedded target. The requirements can include temporal properties to define complex timing-dependent signal logic and can be incomplete or inconsistent. This can lead to errors and miscommunication in the design and test.

This talk shows you how you can model requirements and use the Logical and Temporal Assessments editor in Simulink Test™ to translate informal text requirements into unambiguous assessments with clear, defined semantics that can identify inconsistencies. The temporal assessment language, based on metric temporal logic, provides precise, formal semantics that is highly expressive and extensible to author readable assessments. You will learn how to enter assessments with conditions, events, signal values, delays, and responses using the interactive form-based editor. You can view the assessment in an English language-like statement that is easy to understand or view graphical representations that allow you to visualize the results and debug design errors.

A multi-target tracker developed for surface target tracking in a coastal surveillance scenario needs a robust track initiation and maintenance algorithm for tracking small targets and reducing the false alarm rate in the presence of sea clutter. The multi-object tracks in Sensor Fusion and Tracking Toolbox™ are evaluated with time-stamped detections recorded from the field. The GNN and ToMHT tracker module parameters are tuned by varying track initiation methods, estimation filters, thresholds, and hypothesis maintenance parameters. The resulting track data from each approach is benchmarked with recorded track data from the OEM system in the field. The performance of the MATLAB^® tracker is compared with reference to Track ID maintenance, accuracy in estimated position, speed, course of targets, and time taken for processing each scan data. The results from multi-track line GNN and ToMHT approach with customized EKF and IMM-EKF are found satisfactory with respect to Tack maintenance and kinematics. To improve processing time, sub-optimal assignment methods and custom cost-matrix computation is tried out. The covariance fusion function in SFTT is used for correlating similar confirmed tracks from different tracking lines and removing duplicate tracks from confirmed track list. Code generation from MATLAB Coder™ is used for generating a C++ library with tuned tracker parameters. A wrapper function is written in C++ for interfacing radar detection input and track output to display. Further, custom enhancements are incorporated in C++ deployable code for improving track maintenance and processing time with respect to one scan data. The deployable tracker module is interfaced with a radar in the field and performance evaluation is in progress. An attempt is made to tune tracker parameters generated in C++ library to adapt to present environment conditions based on input data attributes. A display interface is provided for the operator to tune thresholds for reducing false alarm rate.

The technology required to design and field a multifunction radar drives a corresponding increase in system level complexity. In addition to performing multiple radar-related tasks such as search and track, these systems are often called upon to do other applications such as weather observations, communications, or EW, all with the same hardware resources. To meet the desire for shorter development cycles, modeling and simulation early in this type of project can lower risk and accelerate the pace of project.

The advantage of leveraging machine learning techniques in digital pathology is that it provides the capability to learn, to extract knowledge, and to make predictions from a combination of heterogeneous data (i.e. the histological images, the patient history, and the omics data). The ability to mine sub-visual image features from digital pathology slide images—features that sometimes may not be visually discernible—offers the opportunity for better quantitative modeling of disease appearance, and hence, possibly improved prediction of disease aggressiveness and patient outcomes.

Onward Health has built a tool with expert doctor inputs, state-of-art computer vision techniques, and machine learning algorithms. The imaging algorithms are designed to detect different types of cells. Once detected, the algorithm also processes each cell to determine various properties, such as shape, texture, color distribution features, and distance to tumor and other spatial neighbors. The tool employs machine learning techniques to:

• Automatically identify the location of tumor or stroma
• Cluster patients based on their survival probabilities or risk score similarity
  
• Combine the image features along with other patient-related features, such as age, gender, history, medications, and genetics, to extract different types of insights and inferences

The company’s vision is that the tool would enable multiple benefits, including providing and improving cross-verifiable evidence for tumor, better resource management, and aiding the research/knowledge of tumor behavior.

With increasing complexity and the continuously evolving control systems of the current automotive domain, it is becoming tedious to develop and maintain different application software with the conventional methodology of handwritten C code. It even becomes difficult to use it for technology demonstration projects where time is a critical factor. To address this challenge, the model-based development approach is gaining traction among Tier 1/OEMs. Automatic verification and validation and code generation make the development process much more efficient and effective. This not only saves the time required for the development, but it also avoids error-prone hand-coding. Error prevention and early error detection is achieved using model-based development.

In this talk, a model-based approach for application software is discussed where the control system is developed using Simulink^®, Stateflow^®, and MATLAB^®. For better optimization, standard library functions are created and reused in various sub-modules. Studies from requirement traceability to control function development and tagging with test case are being done using Simulink. To maintain the traceability of the models to system requirements, the description of the functionality is written in Simulink blocks when modelling is completed. In this way, ambiguity between the model developed and the system requirements is eliminated, and higher coverage is achieved.

They are able to run AI-based engine models in software-in-the-loop and are planning to build in ECU and test in the vehicle.

Nikhil Khadloya, Cognizant Technology Solutions

Cognizant Technology Solutions has developed an interface for all sensors in MATLAB^® and Simulink^® and established vehicle communications using a high-end automotive grade CPU. This CPU allows the company to run the Simulink model in real time and test the ADAS features along with sensors on the vehicle in real-world driving scenarios. The company calls this technique model-in-vehicle (MIV) validation. MIV leads to in-vehicle verification and validation of algorithms for difficult-to-replicate scenarios in the virtual world in early stages of development in parallel to classical methodology of model-in-the-loop (MIL), software-in-the-loop (SIL), and hardware-in-the-loop (HIL).

The control strategy for an automated manual transmission is tested using a gearbox model running on a hardware-in-loop (HIL) system. The gearbox is a part of a parallel hybrid (P2) powertrain configuration. The gearbox plant model uses components from Simscape™ and Simscape Driveline™ libraries of Simulink^®. The plant model can simulate gearshift forces, including synchronization forces; shift and select detent forces; shift fork leverages, and rotational and translational inertias; and shift sleeve free fly, dog clutch engagement. Gearshift is performed using two electromechanical actuators, one for shifting and other for selecting rail. Detailed models of actuators are also created using data provided by the supplier. Actuator models are validated against their technical specifications like full-load speed, no-load speed, and current drawn at various loads. The control software for AMT is designed in Simulink and Stateflow^® using Model-Based Design. The control software is flashed on a rapid prototyping ECU. The plant model consisting of the gearbox and the gearshift actuators runs on HIL.

Sagar Shriram Salwe, Sooktha Consulting Private Limited

The team at Sooktha Consulting Private Limited is developing physical layers of 5G NR in an agile fashion. The physical layer being a key component of their base station product and very complex, it is extremely important to test the implementation against an established reference before they even integrate with an RF front-end or attempt to interoperate with third-party implementations of the UE side. Further, if they notice issues when interoperating with third-party UEs, they need a reference to validate their implementation in those scenarios. The team is expecting their MATLAB^® implementation to act as the reference that they use to both speed up their implementation as well as to validate it. Finally, to be able to customize their product to India’s rural connectivity or Internet of Things deployments, they may have to define new algorithms or waveforms and need a reliable reference platform to develop and test these algorithms and waveforms. They are planning to use 5G Toolbox™ and other packages as the reliable reference platform on which they can confidently design and analyze different algorithms and waveforms on the basic 3GPP 5G NR technology and contribute to the specifications through TSDSI and 3GPP.

Kaushal D. Buch, Giant Metrewave Radio Telescope, NCRA-TIFR

Giant Metrewave Radio Telescope (GMRT) is one of the most sensitive instruments in the world for observing celestial objects at radio frequencies. A project proposal called the Expanded GMRT (eGMRT) is aimed at enhancing the scientific capabilities of the GMRT. eGMRT aims to expand the field-of-view of the telescope using a multi-element feed at the focus followed by a beamformer. During the prototype development phase, the team at NCRA-TIFR is building a FPGA-based Focal Plane Array (FPA) beamformer in the L-band with 300 MHz bandwidth and an ability to process 30 independent beams using 144 antenna elements.

The development of the FPA beamformer utilizes MATLAB^®, Simulink^®, and other MathWorks toolboxes for antenna array simulation, optimization of beamformer weights, FPGA implementation, and data analysis. The simulation of closely-spaced Vivaldi antenna array was carried out using Antenna Toolbox™ and Phased Array System Toolbox™. A GUI-based simulation tool was developed for the simulation of the radiation pattern through user-configurable antenna selection and array configuration. It also helped in understanding the radiation patterns of beams at different offsets from the direction of the main beam and served as a reference for comparison with the results from the practical beamformer testing.                                                  

The digital design of the beamformer system was carried out using a model-based approach in Simulink. Xilinx^® System Generator blocks were used for implementation of the design. This approach significantly reduced the development time and helped in addressing the incremental changes and debugging.                                                                                         

In this presentation, Kaushal D. Buch describes the array simulation technique, model-based implementation of the beamformer, and recent results from the ongoing prototype development. The presentation also describes how different MathWorks products are useful to a project which uses antenna theory, signal processing, and FPGA design.

Shivaram NV, Ather Energy

Ather Energy has set out to make a change in the way people perceive electric vehicles. Everyone knows that electric transport is the future, but lack of good products in that space in our country is generally hindering faster adoption of electric vehicle technology. A good product has multiple dimensions that need to be met across performance, user experience, and customer service. The Ather 450, along with their charging infrastructure Point, is the first product out of their factory that looks to meet these dimensions.

The scooter, along with charging infrastructure, creates a complex ecosystem of devices where the interaction between these need to be handled well to optimize performance. The company knew the complexity of the system well enough early on, and for them, it was an easy decision to use MathWorks products. The physical model of the system and the algorithm developed went a long way in helping Ather Energy understand and optimize the performance faster.

A multi-target tracker developed for surface target tracking in a coastal surveillance scenario needs a robust track initiation and maintenance algorithm for tracking small targets and reducing the false alarm rate in the presence of sea clutter. The multi-object tracks in Sensor Fusion and Tracking Toolbox™ are evaluated with time-stamped detections recorded from the field. The GNN and ToMHT tracker module parameters are tuned by varying track initiation methods, estimation filters, thresholds, and hypothesis maintenance parameters. The resulting track data from each approach is benchmarked with recorded track data from the OEM system in the field. The performance of the MATLAB^® tracker is compared with reference to Track ID maintenance, accuracy in estimated position, speed, course of targets, and time taken for processing each scan data. The results from multi-track line GNN and ToMHT approach with customized EKF and IMM-EKF are found satisfactory with respect to Tack maintenance and kinematics. To improve processing time, sub-optimal assignment methods and custom cost-matrix computation is tried out. The covariance fusion function in SFTT is used for correlating similar confirmed tracks from different tracking lines and removing duplicate tracks from confirmed track list. Code generation from MATLAB Coder™ is used for generating a C++ library with tuned tracker parameters. A wrapper function is written in C++ for interfacing radar detection input and track output to display. Further, custom enhancements are incorporated in C++ deployable code for improving track maintenance and processing time with respect to one scan data. The deployable tracker module is interfaced with a radar in the field and performance evaluation is in progress. An attempt is made to tune tracker parameters generated in C++ library to adapt to present environment conditions based on input data attributes. A display interface is provided for the operator to tune thresholds for reducing false alarm rate.

The advantage of leveraging machine learning techniques in digital pathology is that it provides the capability to learn, to extract knowledge, and to make predictions from a combination of heterogeneous data (i.e. the histological images, the patient history, and the omics data). The ability to mine sub-visual image features from digital pathology slide images—features that sometimes may not be visually discernible—offers the opportunity for better quantitative modeling of disease appearance, and hence, possibly improved prediction of disease aggressiveness and patient outcomes.

Onward Health has built a tool with expert doctor inputs, state-of-art computer vision techniques, and machine learning algorithms. The imaging algorithms are designed to detect different types of cells. Once detected, the algorithm also processes each cell to determine various properties, such as shape, texture, color distribution features, and distance to tumor and other spatial neighbors. The tool employs machine learning techniques to:

• Automatically identify the location of tumor or stroma
• Cluster patients based on their survival probabilities or risk score similarity
  
• Combine the image features along with other patient-related features, such as age, gender, history, medications, and genetics, to extract different types of insights and inferences

The company’s vision is that the tool would enable multiple benefits, including providing and improving cross-verifiable evidence for tumor, better resource management, and aiding the research/knowledge of tumor behavior.

Autonomous vehicles and driver assistance systems are becoming increasingly popular and the future of the automotive industry with RADAR as critical sensor. Design verification of such sensor products is extremely challenging involving wide variety of Digital, Analog and RF IPs and enormous configuration use cases. Current verification practices are highly focused from Hardware implementation perspective and hence reproducing the field issues faced during Design-In activities is becoming extremely challenging. The key reason for this challenge is the gap existing between the V&V environments used in IC development phase and the environment in which our “Sensor Product” is validated. This presentation is targeted to illustrate a Novel Methodology of “Environment in Loop V&V” which is aimed at modelling the “ON ROAD” scenario and bring the ON ROAD Reflections back to current V&V flows either in the form of Analog inputs, or Digital ADC outputs. This way we can enable Early design-in trails as part of our IC development phase in simulation world.

In our project, we use a radar as a sensor model. The radar is virtually modelled in MATLAB, and the parameters are a reflection of our hardware specification. The radar model is then placed in a virtually modelled environment which closely resembles the outside world.

Full-Duplex communications is a lucrative way for doubling the available system bandwidth. However, Self-interference is a major impediment for realizing a FD node. The interference has to be cancelled at RF, analog domain and the baseband. This requires simulation of the entire RF chain along with impairments. In this session, we use SimRF to simulate the RF chain and also demonstrate the cancellation using a combination of algorithms in the base band and RF units.
