PWM电液位置控制系统自调整模糊控制器的研究

A Study of Self-Tuning Fuzzy Controller for the PWM Electrohydraulic Position Control System

本文针对四个高速开关阀为核心的PWM电液位置控制系统，设计了连续型模糊控制器，构成了实时控制系统。在此基础上，采用启发式搜索算法对模糊控制器比例因子在线调整。实验证明了该控制器在PWM电液位置控制中的有效性。

In this Paper, a continuous type fuzzy controller(FC) is designed for thePWM electrohydraulic position control system which is mainly composed of four highspeed switching valves. A real-time control system is constructed. Thereafter, the scal-ing factor of FC is adjusted on-line by means of heuristic search algorithm. Experimentsshow the validity of the fuzzy controller in PWM electrohydraulic position control sys-tem.
