摘　　要：永磁同步电机(PMSM)结构简单、运行稳定、功率密度大,广泛应用于高性能调速系统。笔者以PMSM为控制对象,分别设计了电流环PI控制器、速度环PI控制器,为了满足系统的工程应用要求,还给出了电流环、速度环控制器的参数整定方法,整定出满足系统控制要求的控制器参数,然后在MATLAB/Simulink中建立了PMSM矢量控制系统仿真模型。仿真结果表明:所设计的控制器具有较好的动态性能和稳态性能,抗负载扰动性能良好。Permanent magnet synchronous motor(PMSM)has the advantages of simple structure,stable operation,high power density,and is widely used in high-performance speed control systems.The author takes PMSM as the control object,and the current loop PI controller and speed loop PI controller are respectively designed.In order to meet the engineering application requirements of the system,the parameter tuning method of the current loop and speed loop controller are given,then PMSM vector control system simulation model is established in MATLAB/Simulink.The simulation results show that the designed controller has good dynamic performance and steady-state performance,and has good anti-disturbance performance.
