摘要: <正> 变结构控制系统是50年代由苏联人首先提出的一种控制方案。它为系统的综合提供了一种新方法,目前已成为控制理论的新分支——变结构系统理论。 变结构系统(VSS)的主要特征是在给定切换域内控制是不连续的,且保证滑动模态存在。主要优点是控制简单易于实现;当滑动模态发生时,其方程对参数变化不敏感。缺点是有抖振现象。

Abstract: The output problem of linear systems is studied by making use of variable structure control in this paper. The output sliding mode compensator is proposed, the output sliding mode equation and its properties are considered. And then the synthesis of switching function and control are given by applying sliding mode state observer and sliding mode dynamic compensator. It is shown that the output sliding mode equation is insensitive to parameter variations and disturbances while the sliding mode oc
