We propose a control algorithm for air cylinder actuator which has normal PID controller with variable offset pressure controller, so as to achieve the high speed response and less overshoot. The is used constant in conventional algorithm, gives stiffness piston. Our therefore adopted time-variant each chamber, that properly increase or decrease according target. experimental results showed rise time was almost same of but tracking improved by 40% compared when lamp target more moderate.
