不确定组合时滞系统的鲁棒分散可靠控制

摘要

研究一类不确定组合时滞系统的状态反馈鲁棒分散可靠控制问题，系统包含状态时滞，非线性扰动和参数不确定性。目的是设计分散线性无记忆状态反馈控制器，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 isinvestigated for a class of uncertain interconnected system with time-delay. The system under consideration involves state time delay, nonlinear perturbation and parameter uncertainties. The aim is to design the linear memory less state feedback decentralized 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 and simulation shows that the method is effective.
