摘要

Because the switched reluctance motor (SRM ) is a doubly salient structure ,hysteresis effect in the operation , eddy current and magnetic path saturation resulting in a highly nonlinear ,and the influence of these nonlinear factors the switch reluctance motor operating efficiency .In order to improve the operation efficiency of the motor ,the nonlinear mathe‐matical model of the motor is established according to the nonlinear factors of the motor ,and the Matlab simulation of the switched reluctance motor is carried out by using the model .Simulation results demonstrate the validity of the proposed mod‐el .The model provides the basis for the control strategy of the switched reluctance motor in the future .%由于开关磁阻电机的双凸极结构，在其运行中的磁滞效应、涡流、磁路饱和等产生了高度的非线性，而这些非线性因素的影响使开关磁阻电机的运行效率。为提高电机运行效率，根据电机的非线性因素采用拟合函数建立电机的非线性数学模型，用建立的这种模型进行了开关磁阻电机 Matlab 仿真。仿真结果证明了该模型的有效性。该模型为今后优化开关磁阻电机的控制策略提供了依据。
