摘要
研究一类不确定关联时滞系统的分散可靠控制设计问题。系统包含状态时滞,非线性扰动和参数不确定性。目的是利用LMI方法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所给结果的有效性。
The problem of decentralized reliable control is investigated for a class of large-scale interconnected uncertain systems with timedelay. The system under consideration involves state time delay, nonlinear perturbation and parameter uncertainties. The purpose is to design a linear memoryless state feedback decentralized controller such that, for all admissible uncertainties and actuator failures occurring among the prespecified subset of actuators, the closedloop system is asymptotically stable. Finally, a numerical example is presented to illustrate the results given and the simulation shows that the method is very effective.
