Description
Summary:This paper overviews surrogate model-assisted multi-objective design optimization techniques of electrical machines for efficient, accurate, and robust design optimization to ease design issues due to unprecedentedly increasing machine performance requirements. Firstly, the mechanism of surrogate-assisted modeling is introduced by comparing it with conventional physical modeling approaches. The relevant techniques are then categorized and subsequently reviewed in terms of the design of experiments, surrogate model construction, and multi-objective optimization algorithms. The potential application prospects for machine design optimization are highlighted. Finally, three surrogate-assisted modeling methods, i.e., transfer learning-based models, gradient sampling-based multi-fidelity models, and search space decay-based surrogate models, are quantitively compared by applying them to the design optimization of a five-phase permanent magnet synchronous machine. •A comprehensive review of recent advancements in data-driven design optimization for electrical machines.•Categorization and analysis of various techniques, offering a thorough perspective.•A concise overview of the potential applications of surrogate-assisted optimization in electrical machines, covering multi-physics simulations, driving cycle-based designs, robustness enhancement, and topology optimization.•Quantitative assessment of three surrogate-assisted modeling techniques applied to a five-phase permanent magnet synchronous machine.
