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, modelling and simulation, and automatic code generation
• Integration into the final engineered system

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

Matt Ley, Rolls-Royce

Rolls-Royce Control Systems is implementing a development process transformation project, called ECOSIStem. It aims to achieve a step-change in quality, whilst reducing development cost and lead-time, through the introduction of Model-Based Product Lines for all on-engine software. This new process will maximise reuse in designs at all levels, from high-level operational concepts through to DO-178 certification evidence. The time to market for novel products, such as Hybrid Aero Propulsion, Intelligent Engine, and IoT services, is also being improved by ECOSIStem.

In this talk, Matt Ley discusses what this change means for his organisation and how it is being put into practice. ECOSIStem is a multi-year project, staffed by a dedicated team, with delivery responsibility to mainstream programmes. It has presented opportunities to introduce principles from modern development methodologies, such as Agile and Lean, into the organisation.

ECOSIStem has allowed the team to rethink where design detail is captured and avoid over-specification, in particular between systems and software. This has been built on the combination of System Composer™ and Simulink^®. Throughout the project, the ECOSIStem team has worked closely with MathWorks to shape the capability of System Composer.

Ilya Kuprov, University of Southampton

The Spinach Toolbox is a fast open-source spin dynamics simulation library written in MATLAB^® that enables thousands of researchers worldwide to run quantum mechanical modelling of magnetic systems. This toolbox is developed by the Spin Dynamics Group (http://spindynamics.org) at Southampton and makes extensive use of both parallel computing and sparse matrix arithmetic on GPUs to simulate microscopic magnetic processes. The package solves Liouville - von Neumann equation (an extension of Schrodinger's equation to ensembles), whose general solution is known but can be very hard to compute because complexity scaling is exponential. The way forward is to approximate using linear scaling methods. This presentation gives a few examples of these extreme scale simulations and discusses their implementation in parallel MATLAB.

Paul Peeling, MathWorks

Engineering teams have more data available to them than ever before. Data from tests, operations, production, and other sources present opportunities for data-based design decisions and new data-based products and services. But many teams struggle to come up with a consistent set of tools and processes for extracting value from this data.

This talk presents a variety of new MATLAB^® features for accessing, organizing, and analyzing data, with a special focus on the MATLAB datastore framework for working with large collections of files and MATLAB datatypes for organizing and preprocessing sensor data. See how these tools enable engineering teams to grow from ad-hoc data analysis to building centralized tools for organisation-wide use, laying a foundation for production apps and analytics.

Samuel Bailey, Skyrad Consulting

The Internet of Things (IoT) is an exciting and rapidly growing segment of the tech economy. Skyrad has invented several IoT sensors, including LeakBot (www.leakbot.io), a clip-on flow sensor, and HeatDoctor, a remote central heating diagnostics system.

During the development of these products, Skyrad explored a number of different approaches. These included running prototype MATLAB^® algorithms in the cloud, translating MATLAB code to embedded C code by hand, deploying algorithms with MATLAB Production Server™, and ultimately running algorithms on the smart sensors themselves, designed using Simulink™ and deployed using Embedded Coder^®.

Samuel will share how Skyrad developed the product, why they chose the particular architecture at each stage, and what was successful (and less successful). He will also give advice to anyone looking to develop or deploy IoT systems, and to anyone who is looking to deploy MATLAB in the cloud.

Mark Walker, MathWorks

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 used to drive a system decomposition and requirements allocation process. Then trade studies are performed on system architecture alternatives to produce a candidate architecture from which the design is developed and then simulated to verify the requirements are met.

This presentation shows how MATLAB^® and Simulink^® support this workflow when combined with Simulink Requirements™ and System Composer™ 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

Peenki Rani, Cummins Generator Technologies

Cummins Generator Technologies (CGT, established 1904) designs, manufactures, and validates alternators under the renowned brands of STAMFORD and AvK. Based in Stamford, Lincolnshire, UK, CGT has branch manufacturing plants in Romania, India, and China. With a nominal 7.5 to 11,200kVA range, CGT alternators are suitable for a variety of applications.

In the modern business environment, to achieve product reliability and commercial growth, a company must be able to accurately simulate and analyze machine performance across multiple varied, realistic conditions in a low-cost and time-efficient manner. MathWorks products offer an integrated simulation environment for Model-Based Design. Simscape™, Simulink^®, and MATLAB^® provide the blocks, tools, and algorithms for efficiently designing and testing physical and control systems.

In this talk, Peenki describes how using Simscape products to develop multidomain synchronous machine models allowed CGT engineers to shorten the alternator design cycle. The models, calibrated using validated field data, allowed CGT to accurately and efficiently predict the transient response for the synchronous machines over a range of alternator fault conditions.

Rick Hyde, MathWorks

Most new electrical and electromechanical systems require multiple models to support the key design questions. Simple behavioural models that enable optimization of the overall system are required early in the design. As a design matures, the system-level assumptions must then be validated by more detailed subcomponent models. Moreover, subcomponent design itself requires more detailed models to ensure constituent parts stay within permitted operating envelopes, thus helping ensure the subcomponent will be reliable in service.

In this presentation, Rick will show how to develop Simscape™ models with different levels of fidelity that span system, control, and component design tasks. Models of both a photovoltaic generator and an electric traction drive will be used for illustration. Workflows to import SPICE subcircuits and magnetic finite element data will be shown, plus abstraction methods to map this detailed design data to support design validation at the system level. Two ways of extracting stability margins from switched converter models will also be demonstrated. The presentation will conclude with a tutorial Simscape language example on how to build a faulted component model.

Designing and deploying deep learning and computer vision applications to embedded GPU and CPU platforms like NVIDIA^® Jetson AGX Xavier™ and DRIVE AGX is challenging because of resource constraints inherent in embedded devices. A MATLAB^® based workflow facilitates the design of these applications, and automatically generated C/C++ or CUDA^® code can be deployed to achieve up to 2X faster inference than other deep learning frameworks.

This talk walks you through the workflow. Starting with algorithm design, the algorithm may employ deep learning networks augmented with traditional computer vision techniques and can be tested and verified within MATLAB. Bring live sensor data from peripherals devices on your Jetson/DRIVE platforms to MATLAB running on your host machine for visualization and analysis. Deep learning networks are trained using GPUs and CPUs on the desktop, cluster, or cloud. Finally, GPU Coder™ and MATLAB Coder™ generate portable and optimized CUDA^® and/or C/C++ code from the MATLAB algorithm, which is then cross-compiled and deployed to Jetson or DRIVE, ARM^®, and Intel^® based platforms.

Verification that a design meets its parent requirements is a significant part of the engineering lifecycle, particularly in high-integrity applications. Verification of a design may be complicated by several factors: the sheer number of requirements, many-to-one mappings between requirements and tests, re-verification following design changes, unintended impact of design changes, and dependency upon both plant (hardware) and control (software) in closed-loop. This master class looks at some advanced techniques using the latest capabilities of Simulink Test™ and Simulink Requirements™ to simplify the verification process. Topics covered include:

• New capabilities for authoring temporal assessments
• Use of advanced features such as tags, types, attributes, and keywords
• Programmatic capabilities of Simulink Test and Simulink Requirements
• Latest support for continuous integration
• Reporting – with customisation

This session is primarily aimed at those with some familiarity of Simulink^® and the verification tools.

Matthew Offredi, BAE Systems
Rayner Saggers, BAE Systems

As the number of MATLAB^® and Simulink^® users grow in an organisation, retaining awareness of an engineer’s developing skills, and the models and code generated, is challenging. Duplication of effort occurs between users and time is wasted by multiple users reinventing the wheel. Cultural challenges exist in the adoption of new tools and bringing the whole engineering workforce along on the wave of change. A user community facilitates knowledge sharing and provides methods for greater communication, education, and standardisation of common working practices. The resulting benefits drive productivity and efficiencies while cutting through the organisation complexities. This presentation discusses the approaches taken at BAE Systems, a large and diverse organisation, to establish a vibrant, self-organising user community to support sharing, self-learning, and personal development.

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.

Predictive maintenance reduces operational costs for organizations running and manufacturing expensive equipment by predicting failures from sensor data. However, identifying and extracting useful information from sensor data is a process that often requires multiple iterations as well as a deep understanding of the machine and its operating conditions.

In this talk, you will learn how MATLAB^® and Predictive Maintenance Toolbox™ combine machine learning with traditional model-based and signal processing techniques to create hybrid approaches for predicting and isolating failures. You will also see built-in apps for extracting, visualizing, and ranking features from sensor data without writing any code. These features can then be used as condition indicators for fault classification and remaining useful life (RUL) algorithms.

Predictive maintenance algorithms make the greatest impact when they are developed for a fleet of machines and deployed in production systems. This talk will show you how to validate your algorithms, then integrate them with your embedded devices and enterprise IT/OT platforms.
