基于论域自调整的模糊PID开关磁阻电机控制系统研究

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.

Fuzzy PID Control System Based on Adaptive Universe for Switched Reluctance Motors

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.
