一类非线性不确定系统的鲁棒观测器设计
Robust Observers for A Class of Nonlinear Uncertain Systems
-
摘要: 对于一类非线性不确定系统,给出一种基于观测器的鲁棒稳定控制器设计的新方法,它适 用于一般匹配不确定系统,且对全维和降维两种观测器均进行了研究.设计实例表明,所设计 的控制器反馈增益幅值较小、实现方便.Abstract: In this paper, a new method of designing observer-based robust stabilizing controllers for a class of nonlinear uncertain systems is presented. It is applicable to the uncertain system which only satisfies the general matching conditions. Both full-order and reduced-order observers are considered. Examples show that the resulting controller has smaller feedback gains and is, therefore, easier in implementation.
