摘要

针对一类不确定的短时延网络控制系统，利用全阶状态观测器作为对网络诱导时延的补偿，定义了一个新的状态变量，得到了短时延网络控制系统的离散模型．根据Lyapunov稳定性理论和矩阵知识，给出该闭环系统渐近稳定的充分条件，并基于线性矩阵不等式的可行解给出了状态反馈控制律．仿真结果表明该方法有效可行．

Abstract

Considering a class of uncertain networked control systems with short time-delay，it proposes a discrete model，in which a full-order observer is utilized to compensate network-induced delay，by defining an augmented state vector，based on Lyapunov stability theory and matrix theory．Sufficient conditions for asymptotic stability of closed．1oop systems were derived，and the state~edback controller was obtained，based on the feasible solution of the linear matrix inequalities(LMI)．The simulation results verify the validity of the proposed method．
