摘　　要：为了简化控制和降低成本,对开关磁阻电动机(SRM)采用电压斩波控制方式;针对SRM转矩脉动大的问题,采用模糊控制器对SRM的关断角进行实时补偿,达到减小转矩脉动的目的。分析SRM非线性数学模型,在MATLAB/Simu link中建立基于电压斩波及关断角补偿控制的开关磁阻电动机调速系统(SRD)仿真模型。最后通过仿真,验证了电压斩波控制方式的正确性,也验证了文中减小SRM转矩脉动方法的可行性和有效性,为实际的SRD设计和调试提供有效的手段和工具。In order to control easily and reduce the cost, a switched reluctance motor is controlled by voltage PWM . To resolve the problem of torque tipple in a Switched Reluctance Motor , a fuzzy - logic - based turn - off angle compensator for torque tipple reduction is proposed. Analyzing the nonlinear math model for a switched reluctance motor, in Simulink, a Switched reluctance motor drive under turn - off angle compensation and chopped voltage control is modeled. Finally chopped voltage control proves to be effective. And the method of reducing torque tipple proves to be reasonable and valid by simulation results. This simulation offers a valid tool for designing and debugging actual switched reluctance motor drive.
