提高电液伺服系统阻尼比的状态观测器方法

Method for State Observer to Improve Damping Ratio of Electrohydraulic Servo System

本文提出一种用状态观测器增大电液伺服系统阻尼比的方法，并对一实例进行了计算机仿真分析。同时，比较了在动力机构的阻尼比和系统开环增益改变情况下带观测器和不带观测器闭环系统时间响应的性能。

In this paper, the method using a state oberver is presented which can improve the daming ratio of a electrohydraulic servo system,and the computer aimulation analysis is carried out on a working example.When the daming ratio of a dynamic mechanism and the open loop gain of a system vary,the time response propertise are compered between closed system with observer and without observer.
