Robust Stability of Feedback Control for Linear Systems With Structured Uncertainty
-
摘要: 本文研究了具有结构不确定性(Structured Uncertainty)因素的反馈控制系统的鲁棒稳 定性问题,对于一个普通的补偿器,给出了闭环系统鲁棒稳定的充要条件,当补偿器满足某些 假设条件时,得出了闭环系统鲁棒稳定的有限检验的充分必要条件.Abstract: The synthesis for structured uncertain systems is an important research area of robuscontrol. This paper deals with robust stability of feedback control of linear systems with structured uncertainty. We present a necessary and sufficient condition of closed-loop systems for a general compens a tor, and if the compensator satisfies some assumption's, a finite checking for robust stability of closed-loop systems is obtained.
