基于Matlab的自适应模糊PID控制器的设计

Design of a self-adaptive fuzzy PID controller with Matlab

将PID控制与模糊控制的简便性、灵活性以及鲁棒性结合起来,设计了一种自适应模糊PID控制器。该控制器可根据给定的偏差范围自动实现PID控制与模糊控制的切换。通过Matlab仿真表明,该控制方法提高了非线性系统的动、静态特性,使系统获得良好的性能。

A self-adaptive fuzzy PID controller, which has simpler structure and higher robustness, is built when fuzzy logic controller and PID controller are combined together appropriately. It can switch between fuzzy contro! and PID control according to the range of error automatically. The results of simulation show that the controller has improved dynamic and static performance of nonlinear control system and has obtained good control quality.
