| Abstract: | In this paper,a pneumatic actuator position servo system is described,which controlled by a five-point switch PWM control method using high-speed switching valves. The switching hysteresis of switching valve is analyzed,and an improvement method is presented which can diminish the static error of the system effectively. The experiment shows that the high-speed switching valve can make the pneumatic actuator position servo system control act promptly,fast and accurately. |
