System-Level Robust Design Optimization of a Permanent Magnet Motor Under Design Parameter Uncertainties

초록

In the presence of design parameter uncertainties, a system-level robust design optimization (RDO) method for a permanent magnet motor is proposed to enhance steady and dynamic performances of the whole motor drive system. To achieve the goal, the influence of individual motor parameters on transient system responses is investigated essentially. Then material characteristic of each motor component due to the operating temperature fluctuation is examined as well. Finally, a conventionally customized motor drive system is fully simulated based on the finite element method, and the motor is optimized by the univariate dimension reduction method (uDRM).
