Abstract
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.
