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.
Automated Physical Model Verification Framework Using Simulink Test
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.

Development of Multi-Target Tracker for Surveillance Radar Using MATLAB
Srihari B R, BEL
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.

Vineet Sharma, Onward Health
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.

Control Software Development and Testing Using MATLAB
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.

Honeywell® IntuVue® RDR-4000 weather radar is an advanced radar system capable of providing 3D display of airborne weather hazards. This is a mechanically scanned radar system capable of providing alerts for weather-related hazards like turbulence and wind shear. It uses sophisticated signal processing techniques to process the raw digitized RF data to produce final weather-related warnings. This is a non-phased array radar system, and hence, not directly amenable to modeling using Phased Array System Toolbox™. Still, the toolbox provides the basic “nuts-and-bolts” to build a sophisticated model.
Developing and Deploying Optimization Strategy for Engine Calibrations
Akansha Saxena, Cummins
Diesel engine calibration is a careful balance of emissions while trying to achieve the lowest fuel consumption possible. In a certain instance of trying to achieve this balance, some areas of the calibration yielded enough smoke to cause EGR cooler fouling issues under the right conditions.
This presentation discusses this challenge for Cummins and how the optimization process and MATLAB® based toolkit was used to improve robustness to smoke while maintaining the rest of the emissions constraints. The Cummins-developed toolkit utilizes many MATLAB toolboxes including Statistics and Machine Learning Toolbox™, Parallel Computing Toolbox™, Optimization Toolbox, and MATLAB Compiler™.
Presently, engine idle control is done by a PID controller at Tata Motors Limited. The company is working to reduce quality of idling (over shoot, under shoot, saturation time, and fuel consumption) by 10% when compared to production vehicles using artificial intelligence (AI) tools from MathWorks. 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.
Model-in-Vehicle Validation Methodology for ADAS Features
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).
HIL Testing of AMT Control Strategy Using Simscape Plant Models
Ajitsinh A. Yadav, Tata Motors
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.

Whirlpool of India Ltd
Whirlpool of India Ltd
In past two years, Model-Based Design has been extensively used at Whirlpool for embedded software development to overcome various difficulties and complexities that typically arise during the design lifecycle of embedded software for closed-loop control systems. With Model-Based Design, Whirlpool can provide a single design environment so that developers can use a single model of their entire lifecycle for data analysis, model visualization, testing and validation, and ultimately, product deployment, with or without automatic code generation.
This presentation discusses how Whirlpool has deployed Model-Based Design, starting with a single platform (home appliances) and spreading across all four different platforms (cooking, dishwasher, and refrigeration), for controls algorithm development due to the numerous advantages the workflow offers. It also explains how the team has brought maturity into the testing process using different MathWorks tools. Whirlpool has deployed a model-based methodology, following these steps:

5G NR PHY Implementation, Algorithm Design, and New Waveform Research in MATLAB
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.
Antenna Array Simulation and Beamforming for the Expanded GMRT
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.
