摘要
本文对永磁同步电机(PMSM)的双闭环控制系统进行了分析。采用矢量控制方式,通过坐标变换来对磁链和转矩进行解耦,形成以转子磁链定向的两相参考坐标系,模拟直流电机的控制方法。结合永磁同步电机矢量控制模型对电流与速度环调节器进行参数整定,并在MATLAB/Simulink中进行仿真分析。仿真结果证明了永磁同步电机矢量控制系统和控制算法的正确性。
The double closed-loop control system for permanent magnet synchronous motor(PMSM)were analyzed.The vector control method was adopted,and the flux linkage and torque were decoupled by coordinate transformation,and a two-phase reference coordinate system oriented by rotor flux linkage was formed for simulation the control method of DC motor.Combined with vector control model of permanent magnet synchronous motor,the parameters of current and speed loop regulator were adjusted and simulated in MATLAB/Simulink.Simulation results showed that the correctness of vector control system and control algorithm of permanent magnet synchronous motor.
