Position Control of a Pneumatic Rodless Cylinder Using Sliding Mode M-D-PWM Control the High Speed Solenoid Valves

Abstract

The purpose of the paper is to apply a control law, which combines the sliding mode and modified differential PWM(M-D-PWM)control method to control the position of a pneumatic rodless cylinder.The experimental results show that the pneumatic system has the advantages both good performance and low cost with the proposed controller.
