Research on Speed Control System of Doubly-Salient PM Motor Based on High-Precision Fuzzy Controller

将高精度模糊控制器的控制方法应用于双凸极电机(DSPM)的调速系统中,与基本模糊控制器相比较,这种方法可以减小调速系统的稳态误差并提高动态响应速度。仿真结果表明,这种控制系统的动态响应速度快、超调量小、稳态误差小、抗干扰能力强。这种方法相当于在基本模糊控制器的基础上引进了一个PI控制器,改善了调速系统的动态性能和稳态性能。

A high-precision fuzzy controller method has been applied in the speed control system of doubly-salient permanent magnet（DSPM） motor.By comparing with the basic fuzzy controller,this method can reduce the steady-state error of the speed control system and improve the speed of dynamic response.The simulation results show that this control system has the advantages of fast dynamic response,low overshoot,small steady-state error and excellent anti-interference capacity.This method is equivalent to add a PI controller based on the basic controller, thus the dynamic performance and steady-state performance of the speed control system are improved.
