摘　　要：针对具有不确定时延的网络控制系统,利用一致有界性理论、线性矩阵不等式方法分析系统一致有界性.首先引入线性离散系统和线性离散时滞系统的一致有界性,提出具有网络不确定时延的NCS系统一致有界性的概念.其次利用一致有界性理论、LMI和Schur补引理,给出网络控制系统一致有界的充分条件,并设计静态反馈控制器使闭环网络控制系统一致有界.最后给出算例,利用Matlab/LMI求解来说明结论的正确性.For with the uncertain delay of networked control systems,this paper analyzes the system of uniform boundedness by the theory of uniform boundedness of linear matrix inequality methods.Firstly,introduces the uniform boundedness of the linear discrete system and the linear discrete time-delay systems,and put forward the concept of uniform boundednes with NCS system of networked uncertain time delay.Secondly,network control system is given the sufficient condition for uniformly bounded by the theory of uniform boundedness,LMI and Schur complement lemma,and then static state feedback controller is designed to make the closed loop network control system is uniformly bounded.Finally,a numeral example is given to verify the correctness of the conclusion by Matlab/LMI.
