摘　　要：使用一种五点开关PWM控制算法对高速开关阀气动执行器进行位置伺服控制。分析了开关阀的启闭滞后现象,并提出了一种修正方法,该方法可有效地消除系统的静态误差。实验结果表明,用高速开关阀可以实现快速、精确的气动执行器位置伺服控制。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.
