Multi Objective Multi Constraint Optimization of Electrical Machines

Yves Thioliere & Shafigh Nategh



Multi-objective multi-constraint optimization is required for the design of high performances electrical appliances because of their need to satisfy a multitude of requirements. Optimization issues such as these perform searches within small and complex regions (design spaces that satisfy all constraints). Multipoint searches such as genetic algorithms (GA) are useful as search methods, but there exists the issue of calculation amounts increasing significantly in size. Pre-processing occurs in the form of narrowing down the design spaces as so to reduce these calculation amounts. However, depending on the way in which this narrowing down takes place, there exists the importance of factors such as experiences, making personal judgements, or risk of those narrowing-down processes not being carried out correctly.
