摘　　要：通过对永磁同步电机的数学模型的分析,结合矢量控制原理,建立id=0控制下的永磁同步电机调速系统的仿真模型,针对被控对象的非线性,参数时变等特性,运用模糊PI控制策略,设计控制器,然后建立仿真模型,验证该方法的优越性。仿真结果表明,模糊PI控制调速系统,响应速度快,超调小,抗扰性好,能更好地提高永磁同步电机的调速系统的性能。Through the analysis of the mathematical model of the permanent magnet synchronous motor,combined with the principle of vector control,Create the permanent magnet synchronous motor speed control system simulation model under the control of id =0.For controlled object nonlinear,time-varying characteristics and using fuzzy PI control strategy,design controller,then build simulation models in order to verify the advantages of the method.Simulation results show that the fuzzy PI control the governor module,fast response,small overshoot and good immunity,can better improve the performance of the speed control system of permanent magnet synchronous motor.
