模糊自整定PID控制器的设计及其应用

A self-tuning fuzy PID controller and its application

以液压伺服控制系统为研究对象,根据模糊控制理论,运用常规PID控制器的设计方法,设计出了模糊自整定PID控制器,实现了PID控制器参数在线自调整.仿真试验表明,该PID控制器与常规PID控制器相比较,提高了控制系统的适应能力和鲁棒性,改善了系统的静、动态性能.

The defects of the traditional PID controller are analysed. The design method of the Fuzzy PID controller based on self-tuning parameters and fuzzy control theory is discussed. By simulation and comparision with other ordinary PID controls, we conclude that the use of the method in a hydraulic servo system can greatly improve the robustness and the dynamic static and properties of the system.
