Research on self-uning regulatorof pneumatic position servo-system with resistant load
自校正调节器在具有阻力负载的气动位置伺服系统中的应用

The pneumatic position servo_system uses gas as transmission medium.But due to the special characteristics of the gas,it is difficult to achieve the accurate control of the servo_system.To study the soft outside force of the cylinder and truly image system control process, a method that uses cylinder to simulate actual resistant load of position servo_system is proposed.The system was described with a three_order model firstly,and the control law with self_tuning regulator was deduced.Then,through experiments,the effect of the self_tuning regulator on system dynamics and static performance was discussed.Finally,based on simulation results,the hysteresis of the system tracking response was analyzed.
