气动比例/伺服位置系统扰动观测补偿控制的研究

Research on the Compensation Control of the Servo-Pneumatic Positioning System by a Disturbance Observer

通过对气动比例 /伺服位置控制系统的静 /动特性的分析 ,提出了用于气动比例 /伺服系统的扰动观测补偿器 ,仿真及实验表明 ,该方法可有效地改善气动比例 /伺服系统的刚性差、抗外界干扰性差等弱点。

In this paper, a disturbance observer compensation control is presented by analyses of the static/dynamic characteristic of pneumatic-servo positioning system. Simulation and experiment demonstrate that the method can improve the low rigid and bad anti-force feature of pneumatic-servo positioning system.
