摘要
分析了开关磁阻电动机调速系统(SRD)的工作原理及开关磁阻电动机(SRM)的非线性电感模型。在此基础上,对其进行了简化处理,并采用模糊控制器对SRM的开关角进行实时补偿,同时建立了基于电流斩波控制的四相SRM非线性仿真模型。仿真结果验证了该控制方式的正确性,该模型不但计算相对简单且能有效减小转矩脉动和提高系统的动、静态性能,并能满足一定精度要求,为实际的SRD设计和调试提供有效的手段和工具。
The principle of switched reluctance motor speed regulating system(SRD) and nonlinear inductance model of switched reluctance motor(SRM) are analyzed.On the basis of this,the model is simplified,and the real-time compensation is carried on SRM switching angle by using fuzzy controller.The four-phase SRM nonlinear simulation model is built based on current chopper control.The simulation results show the effectiveness of the control mode,proving the model calculation is relatively simple,reduces torque ripple and improves the static and dynamic performance of system.The certain accuracy demands can be meet to provide a valid tool for the actual SRD design and debugging.
