摘要

基于状态观测器，讨论了不确定相似组合系统的鲁棒分散输出反馈镇定问题，系统的输入是非理想的，不确定项存在于系统内部和各子系统的关联项中，它们可能是非线性或时变的，且满足通常的匹配条件.使用变结构原理设计控制器，所设计的控制器保证系统渐近稳定.研究结果表明，系统的相似性有助于简化对系统的分析和设计；仿真结果表明，本文的方法是有效的.%The problem of the robust decentralized output feedbackstabilization for uncertain similar composite systems with imperfect inputs based on state observer is investigated. The uncertainties exist in every subsystems and interconnections. These uncertainties may be nonlinear or time-varying and meet the matching condition. The system asymptotic stability can be guarameteed by controller designed with variable structure theory. The system similarity can be help to simplify the analysis and design of the system. The simulation result is shown that the control scheme given in this paper is effectiveness.
