摘　　要：研究一类包含状态时滞和参数不确定性的不确定时滞组合系统基于状态观测器的鲁棒分散可靠控制问题 .目的是设计分散状态观测器和线性无记忆观测状态反馈控制器 ,使得对于任意容许的不确定性以及在每一个子系统中预先指定的执行器子集合内执行器的失效 ,相应的闭环系统渐近稳定 .最后给出一个数值例子验证了本文所给结果的有效性 .The problem of robust decentralized reliable control is investigated for a class of uncertain interconnected system with time-delay. The system under consideration involves state time delay and parameter uncertainties. The purpose is to design the decentralized observer and linear memoryless dynamic output feedback controller such that, for all admissible uncertainties as well as actuator failures occurring among a prespecified subset of actuators, the closed-loop system is asymptotically stable. Finally, a numerical example is presented to illustrate the results given in this paper and simulation shows that the method is very effective.
