PD-fuzzy logic controller design for position control of intelligent pneumatic actuator system

Abstract

Intelligent Pneumatic Actuator is a system that has been developed for application that requires better control and accuracy. The purpose of this paper is to present a controller design for position control of an Intelligent Pneumatic Actuator (IPA) system using Proportional-Derivative Fuzzy Logic Controller (PDFLC) and PID Controller. The controller is designed based on 3rd order transfer function of the system. The performance of the designed PDFLC controller is tested to the actuator position control in MATLAB environment and the results show fast response and good stability. The simulation result is compared and analyzed with PID Controller to illustrate the performance of the proposed controller. The result obtain in this paper are useful towards a proposed Pneumatic Actuated Ball Beam System (PABBS). © 2012 Springer-Verlag.
