Design study of an adaptive Fuzzy-PD controller for pneumatic servo system

摘要

This paper presents a new adaptive Fuzzy-PD controller and researches the adaptability of the Fuzzy-PD controller for a pneumatic servo position control system which has some typical characteristics of nonlinearity and time-varying. A new control algorithm for friction compensation is introduced to enhance the accuracy of pneumatic servo position control systems by means of adjustment of a so-called adaptive controller parameter M_a. Some experiments has been made to show that the adaptive Fuzzy-PD controller can control the pneumatic servo system accurately.
