The application field of the pneumatic systems is limited comparing the electromotive system and the hydraulic one. Because control performance of the pneumatic systems is inferior to the other system. But the pneumatic system has the character which is not present in the electromotive system and the hydraulic system, i.e., high safety and excellent environmental preservation. If the control performance is improved, it will be possible to apply the pneumatic system to every industrial field. In the pneumatic system, the main factors that control performance is especially inferior because the character of the plant changes widely by air compressibility and the difference in the load mass. Therefore, pneumatic servo system cannot accomplish satisfactory control performance by using usual control methods (PID or optimal control methods). So an adaptive control system has been introduced to improve the control performance.
This paper presents a design scheme of an adaptive pole-placement control for pneumatic servo systems. In this design scheme, we used unique method for deciding control parameters. The effectiveness of the proposed design scheme is confirmed by experiments using the existent pneumatic servo system.
