| 摘 要： | 为了实现电液伺服机构驱动速度自动调节，抑制和消除扰动的影响，利用测速电机和电位器作为反馈元件，油缸作为驱动执行元件，PID为核心及相应的信号处理等电路构成观测器重构状态反馈控制元件，构成了等价闭环控制系统，给出了油缸和伺服机构驱动原理及观测器重构状态反馈系统的设计方法和实验过程．经实验证明，本系统能够得到往复直线运动速度自动调节，实现了双杆活塞液压缸对称相等的驱动速度,具有快速抑制和消除系统扰动作用的功效.

| Abstract: | When an asymmetric cylinder is used in an electro-hydraulic servomechanism. The characteristics of the piston velocity are not symmetrical. In this research an rver was designed. This observer which uses control force and velocity of the piston can guess an asymmetric driving force of this system. Then this observer composes a feedback loop in servomechanism. The objective of this research is as follows: 1. Getting the same velochar-acteristics as that in a mechanism with a symmetric cylinder. 2. Explaining how to design the observer and the results of compensation of asymmetrization. |
