基于CMAC的开关型模糊PID控制器设计与仿真

摘要

Aiming at the swith transition phenomenon near the criterion of switching FUZZY-PID control, a strategy of switching FUZZY-PID combined control based on CMAC network is presented . The control method of the switching FUZZY PID control, and the parallel of CMAC-PID and algorithm of the control are expounded in this paper. An AC motor is served as the controlled object.The results of simulation show that the control method has a fast response and short learning time and self-adaptive property. And also the problem of switch transition is solved very well.%针对开关型模糊-PID控制在判据附近出现的开关跳变现象,提出了一种基于CMAC网络的开关型FUZZY-PID控制器.分别阐述了开关型模糊PID控制、CMAC-PID并行控制及本控制方法的原理和算法.以某交流电机为控制对象,通过MATLAB仿真验证表明,该控制方法响应速度快,学习时间短,具有良好的自适应性,并且很好的解决了开关跳变的问题.
