摘　　要： 针对开关磁阻电机(SRM)非线性、变结构、电磁关系难以分析等问题,采用自适应模糊PID控制算法,对SRM调速系统进行研究。文中论述了直接转矩控制、自适应模糊PID控制器的设计,通过SIMULINK进行仿真,并与常规PID控制器下的SRM调速系统进行对比分析。仿真结果表明:基于自适应模糊PID控制器的开关磁阻电机调速系统响应时间短,且动、静态性能良好。 There are serious nonlinear,variable structures characteristic in SRM,so that its electromagnetic relationship is hard to analyze.The control algolithm of self-adaptive Fuzzy PID was employed to research SRM direct speed-regulating system.This paper discussed Direct Torque Control and how to design self-adaptive Fuzzy PID controller,and then adopted SIMULINK to simulate.The simulation results were compared with the system based on conventional PID regulator.The results show that the response speed of SRM speed-regulating system is improved,and the dynamic and static performance is good.
