摘要：针对开关磁阻电机的非线性和强耦合性，为开关磁阻电机设计基于模糊PID控制的鲁棒调速器。详细介绍了PID控制和模糊PID控制，并利用PID控制和模糊PID控制分别在低速、中速和高速时对开关磁阻电机进行调速仿真，仿真对比结果表明模糊PID鲁棒调速器使系统超调量降低至少3%，上升时间能减少约6%，调整时间能缩短20%以上，受扰动的调整时间缩短约30%以上。因此，与传统的PID方法不同的是，基于模糊PID控制方法可以使开关磁阻电机系统具有较快的响应速度，较小的超调量以及更强的鲁棒性。

Abstract: A robust governor is provided for Switched Reluctance Motor (SRM) in presence of nonlinearities, and strong coupling based on fuzzy PID control. At first, PID control and fuzzy PID control were constructed respectively for SRM, moreover, a series of comparison simulations were achieved including low speed, medium speed and high speed. Simulations show robust governor enables the system reduced by at least 3%, 6% and 20% in overshoot, rise time and setting time respectively, besides setting time can be shortened more than 30% for disturbed system. Effectiveness and efficiencies of the fuzzy PID controller was verified by simulations therefore, different from conventional PID control, SRM fuzzy PID control can achieve higher speed of response, smaller overshoot and stronger robustness.
Key words: SRM; PID control; fuzzy PID control
