An adaptive fuzzy controller for a pneumatic servo system

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 and takes its typical characters into consideration and places a special emphasis on the method of compensation for nonlinear friction. A new control algorithm for friction compensation is introduced to reach the goal of improving the accuracy of pneumatic servo position control systems by means of adjustment of a so-called adaptive model parameter Ma. The experiment results show that the adaptive fuzzy-PD controller has better dynamic characters, stronger adaptability and higher position accuracy than conventional ones.
