Abstract

Overall optimization of electromechanical aerospace actuators requires a multiobjective analysis to account for both performance and efficiency, while considering technical costs, due to the conflicting nature of the respective criteria. This paper introduces a particular multiobjective, population-based optimization methodology, using the differential evolution algorithm combined with manufacturing cost and motor-clean-interface related constraints. A magnetic equivalent circuit model is implemented and integrated in the process to account for flux leakage effects. The methodology presents stable convergence characteristics and has been applied to further extend previous work regarding the optimization of a fractional slot concentrated winding surface mounted permanent magnet motor. The resultant motor design has been validated through a prototype and experimental results illustrated its suitability for aerospace actuation.
