摘　　要：针对开关磁阻电机系统较强的非线性,提出了一种基于论域自调整技术的模糊PID控制方法。根据论域自调整理论,设计了论域自调整模糊PID控制器;搭建了开关磁阻电机和论域自调整模糊PID控制器的Matlab仿真模型;通过仿真将开关磁阻电机在传统PID控制和论域自调整模糊PID控制条件下的运行状况进行了对比。仿真分析表明,论域自调整模糊PID控制方法比传统PID控制方法响应速度更快,控制精度更高,抗干扰能力更强。In view of the nonlinear characteristic of switched reluctance motors, a fuzzy PID control method based on adaptive universe technology was proposed, With the adaptive universe theory, the universe-adaptive fuzzy PID controller was designed accordingly. The model of switched reluctance motor and the controller were built on the Matlab. Under the two control methods, universe-adaptive fuzzy PID and traditional PID, the performances of the switched reluctance motor were contrasted. Results of the experiment prove that, compared with the traditional PID controller, the universe-adaptive fuzzy PID controller responds faster, pessesses higher control precision and functions better in terms of anti-jamming.
