实现永磁同步电机的PID闭环控制，能够仿真出来，且波形较好(Realization of Permanent Magnet Synchronous Motor PID Closed Loop Control)

基于dspic系列的永磁同步电机的开发和应用，应用很广，很有用(Based on the dsPIC series of permanent magnet synchronous motor development and application, the application is very wide, very useful)

基于SIMULINK的psms建模，不使用函数语言，通俗易懂(psms modeling based on SIMULINK)
