Abstract: This talk presents an automated design and optimization framework enabled by machine learning (ML) for electric transportation power systems. As these systems become increasingly complex and involve the co-design of multiple inter-dependent subsystems and components, a large amount of engineering time and effort is required to explore all possible designs due to large design spaces. Multi-physical domain models and simulations, essential to measure a given design’s performance, are typically computationally expensive to run – sometimes taking hours to days, depending on the system complexity. Providing an approach to drastically simplify this process – as in time and cost reduction – will allow faster and cheaper research and development throughout the transportation sector. Synergistic integration of advances in machine learning with physical domain knowledge paves one feasible pathway to practically realize this vision. Bayesian optimization (BO) is an effective machine learning framework to solve design automation problems with expensive experiments. This paper proposes a novel BO algorithm referred to as Max-value Entropy Search for Multi-objective Optimization with Constraints (MESMOC) to solve multi-objective optimization (MOO) problems with black-box constraints that can only be evaluated through design simulations. The key idea is to build statistical models of both design objectives and constraints, and use them to intelligently select the sequence of designs for evaluation based on the principle of output space entropy search – maximize the information gain about the optimal Pareto front – to efficiently uncover (approximate) Pareto optimal designs. MESMOC is capable of drastically reducing the number of design simulations to discover a high-quality Pareto front. A heavy-duty vertical-takeoff-landing (VTOL) unmanned aerial vehicle (UAV) power system is selected to demonstrate the effectiveness of the ML-based MESMOC algorithm. In several experimental trials, the ML algorithm uncovered the entire optimal Pareto front while only exploring ~4% of the design space. The proposed ML algorithm, when compared to a popular genetic algorithm, showcases superior performance.

Abstract: In this lecture, a broad review of vehicles for farming operation will be given starting from tillage to crop harvesting. Vehicles that have significant use of power electronics will be covered such as Exact-Emerge Planter for seeding operation followed mention of Exact-Apply for crop care and management of plants (corns etc.) that are nutrient deficient. This will lead discussions towards how power electronics supports crop-care system to exactly apply prescription such as fertilizers, pesticides, fungicide, etc. Discussions of this lecture are targeted to create awareness among power electronics and engineering professionals that how your vocation could enable putting food on plate of 9 billion people by 2050 and provide them shelter and transportation infrastructure. This lecture would also cover how electrification is becoming enabling technology in off-road heavy-duty vehicle space. Discussions of this lecture will cover that how wide bandgap (WBG) power electronics could enable many functions, forms, and features in heavy-duty off-road vehicles such as equipment required for agriculture, construction, and mining operations. The Silicon Carbide (SiC) and Gallium Nitride (GaN) based power electronics indeed could offer system level solution that are performance-superior and cost-competitive compared to state-of-art silicon semiconductor-based power electronics. These system approaches will be mentioned in midst of this presentation.

Abstract: This webinar provides engineers with techniques to develop and construct electromagnetically compatible Wide Bandgap (WBG) power electronic converters used in aviation applications. Real-world examples and issues are demonstrated with high-frequency construction methods necessary to meet the Electromagnetic Compatibility (EMC) requirements. The webinar provides fundamental EMC theory for SiC power electronics, a new “SOLVE” EMC design flow for WBG power converters, and practical design, construction, and measurement techniques.
