基于Fuzzy-PID的双凸极永磁电动机调速系统

Doubly salient permanent magnetic control system based on Fuzzy-PID

针对双凸极永磁电动机调速系统转速与转矩、电流等参数具有很强的非线性关系这一特点,提出了基于模糊PID的双凸极永磁电动机调速系统控制器的设计方法,利用模糊推理对PID控制进行了参数自动整定。仿真结果表明,该模糊PID控制方法具有超调小、响应快、运行稳定等特点;模糊控制与PID控制相结合,能够有效抑制超调,提高系统响应速度和稳态性能,并具有较强的鲁棒性。

Aiming at the case of strong non-linear system such as doubly salient permanent magnetic（DSPM） motor, a new fuzzy- PID controller based on the combination of PID and fuzzy inference for doubly salient permanent magnetic motor system was proposed. Proportional, integral and derivative parameters were adjusted adaptively, according to the error between output and reference. The simulation results show that the approach has more significant performance and robustness than conventional PID controllers.
