摘要
本文研究变结构系统在非匹配条件下滑动模的鲁棒性问题。首先提出了变结构系统部分不变性的概念；进而给出了变结构系统具有部分不变性的充分必要条件；最后举一个例子验证所提出的方法。本文结果解决了不确定系统在何种条件下可以直接设计出具有期望动态品质的滑动模的问题。
This paper addresses the robustness problem of sliding modes for variable structure control systems in which the system uncertainties do not satisfy the so-called matching or invariance conditions. After introducing the partial invariance concept of variable structure systems, corresponding necessary and sufficient conditions, which render the previous invariance conditions a special case,are then obtai'ned. An example is also given to show the robustness of designed sliding mode. The results indicate the conditions under which sliding molde can be designed explicitly to have good dynamic response.
