A Wind Driven Optimization-Based Methodology for Robust Optimizations of Electromagnetic Devices under Interval Uncertainty

A methodology based on a new uncertainty quantization formulation and an improved wind driven optimization (WDO) algorithm is proposed for robust optimizations of electromagnetic devices under interval uncertainties. In the proposed methodology, the robust performances are enforced as the constraint functions, and the objective function is selected as the biasing force to evolve the iteration procedures. The WDO method is also improved to guarantee a good balance between the exploration and exploitation searches. Numerical results on a case study are reported to showcase the feasibility and merit of the proposed methodology in solving practical engineering design problems.
