摘　　要：为了提高电动汽车用开关磁阻电机综合性能,在获得开关磁阻电机磁链特性曲线的基础上建立了其非线性动态模型;以改善平均转矩,降低转矩脉动,提高电机效率为目标,提出了一种多指标同步优化开关角度的方法,建立了最优开通角、关断角与转速、负载转矩之间的函数关系;设计了基于可变开通角、关断角的驱动系统优化控制器;定义了均方根电流比例系数、转矩平顺度比例系数和等效功率比例系数3个概念,将多指标同步优化策略与平均转矩最优化策略进行了对比分析,分析及实验结果表明:利用多指标同步优化开关角度的方法建立的转矩优化控制器能很好地平衡平均转矩、转矩脉动和电机效率3个参数指标,达到了优化开关磁阻电机转矩动态特性的目的。In order to improve and optimize the integrated dynamic performance of the switched reluctance motor(SRM)used in electric vehicles,the nonlinear dynamic model is established after obtaining the flux characteristic curves.A multi-objective simultaneous optimizing switching angle method was proposed to increase the SRM dynamic performance and the optimal turn-on and turn-off angle model as functions of rotor speed and load torque was established.The optimal torque controller of the SRM drive was designed with the variable turn-on and turn-off angle functions.And three coefficients were proposed to compare this method with the average torque optimization method using the optimal torque controller.The comparison and experiment results show that the multi-objective simultaneous optimization controller can effectively improve the integrated dynamic performance of the SRM used in electric vehicles.
