摘　　要：为降低永磁辅助开关磁阻电机(Permanent magnet assisted switched reluctance motor,PMa-SRM)的转矩脉动、提高其平均转矩,提出一种将遗传算法优化的支持向量机(Genetic algorithm optimizes support vector machine,GASVM)与非支配进化算法(Non-dominated sorting genetic algorithmⅡ,NSGA-Ⅱ)结合的混合多目标优化方法。首先介绍了PMa-SRM结构,通过田口法建立了实验样本数据,并通过方差分析分析了开通角、关断角、极靴角对PMa-SRM转矩脉动和平均转矩的影响。然后通过GASVM分别建立开通角、关断角、极靴角与PMa-SRM转矩脉动和平均转矩的预测模型。最后采用了NSGA-Ⅱ对预测模型进行全局寻优,并从NSGA-Ⅱ生成的Pareto前沿中选取最优设计。通过对比优化前后电机的输出性能以及样机转矩与振动实验,验证了运用GASVM-NSGA-Ⅱ优化设计方法的有效性。To improve the performance(low torque ripple and high average torque)of the permanent magnet assisted switched reluctance motor(PMa⁃SRM),a hybrid multi⁃objective optimization method is proposed,which combines the genetic algorithm optimizes support vector machine(GASVM)with non⁃dominated sorting genetic algorithmⅡ(NSGA⁃Ⅱ).Firstly,the PMa⁃SRM topology is introduced.Secondly,the experimental sample data is established by the Taguchi method,and the effects of the turn on angle,the turn off angle and the pole shoe angle on the PMa⁃SRM torque ripple and the average torque are analyzed by variance analysis.Thirdly,the torque ripple and the average torque predictive models between the turn on angle,the turn off angle and the pole shoe angle are established by the GASVM.Next,the NSGA⁃Ⅱis used for global optimization of the predictive models,and the optimal design is selected from the Pareto front which is generated by NSGA⁃Ⅱ.The output performance of the optimized front and rear motors,and the prototype torque and vibration experiment confirm the effectiveness of the optimization design method with GASVM⁃NSGA⁃Ⅱ.
