Improvement of Dynamic Characteristics of Pneumatic Servo System with Fuzzy Control.

Abstract

A pneumatic driving system has been used in the production facilities of various industries. However, high performance can not be easily achieved with these pneumatic systems because of the high nonlinear properties resulting from air compressibility and friction. Therefore it has been used mainly for relatively simple tasks. Recently, pneumatic systems must have high performance since they are used for robotics and mechatronics. As a fuzzy control uses fuzzy rules described with only a qualitative relationship between the input and output of the system without any mathematical modeling, it is considered to be useful for controlled plants with high nonlinear characteristics.
