摘 要：介绍了网络控制系统中的时滞独立系统。利用Lyapunov稳定性定理和线性矩阵不等式（LMI）工具给出了H∞控制器存在的时滞独立网络控制系统的充分条件。通过求解一个具有线性矩阵不等式的凸优化问题，得出γ最小的H∞控制率。仿真实验结果显示，整个系统对干扰信号有较好的抑制作用。

Abstract: Delay independent system of network control system was introduced. The sufficient conditions of the H∞ controller for delayindependent network control systems were given by using the Lyapunov stability theory and the linear matrix inequality (LMI) technique. And the H∞ controller which had the least γ value was gotten by solving a convex optimization problem satisfying linear matrix inequalities. The simulation experiment shows that the whole system has a good performance to reduce the influence of the disturbance.
