摘　　要：本文针对一类不确定的长时延网络控制系统,在系统方程右端加上扰动项,利用李亚普诺夫函数,借助线性矩阵不等式,设计出了使系统具有H∞性格指标的闭环系统渐近稳定充分条件,并设计出了状态反馈控制器,仿真实例表明结论具有可行性与有效性。This paper focus on the uncertain networked control system with long time- delay. The disturbation is added on the right of the state equation. The sufficient condition for the uncertain networked control system with long lime - delay which is subject to the closed - loop system asymptotic stability and H∞ Performance is mainly derived based on the Lyapunov function and Linear Matrix Inequality（LMI） .The H∞ state feedback controller is designed at last.The simulation example for the uncertain networked control system with long time - delay shows the effectiveness and feasibility of the proposed method.
