摘　　要：开关磁阻电动机可控变量较多 ,且变量之间彼此耦合 ,因此要实现电机的电流控制方式 ,不单要研究电流 ,还要研究与之相关的其他变量。该文利用Matlab/Simulink仿真软件的优点 ,建立了通用性强、易修改、具有模块化结构的开关磁阻电动机的动态仿真模型。利用该模型可以方便地实现电机的角度位置控制 ,通过大量的仿真实验 ,形象、直观地揭示了开关角对电流波形的影响 ,进而研究与验证了在电流控制方式下 ,电流波形与电机的转矩和转速之间的关系 ,同时也很好地解决了工程设计中根据电流波形这个可测量来设计最优开关角 。Switched reluctance motor (SRM) is a multi-variable and strong coupling system. To study current control mode of SRM, not only current but also the related variables are under consideration. In this paper, a dynamic simulation model of SRM is developed with Simulink toolbox of Matlab. The model makes the design and modification of parameters more easily. Based on the model, angular position control strategy of SRM is studied. The simulation results show the influence of switch angles on current waveform. Further, the relation between the current waveform and torque and rotor speed of SRM is studied and tested. This work is useful for designing the optimal turn-on and turn-off angles according to the current waveform measured in the engineering design.
