摘　　要：研究了具有线性时不变的被控对象的长时延网络控制系统的H∞控制问题.基于长时延网络控制系统的开关系统模型和不确定参数模型,结合李亚普洛夫稳定性原理和鲁棒控制理论,给出了长时延网络控制系统渐近稳定并具有H∞范数界γ的存在条件,提出了基于线性矩阵不等式的长时延网络控制系统H∞控制器的简便设计方法.最后以网络环境下的不稳定倒立摆为对象进行了仿真研究,结果验证了本文方法的可行性.A controller for networked control systems（NCS） with long time delay was designed and linear time-invariant controlled process was discussed. Based on the switched system model and uncertainty parameters model of networked control systems, the existing conditions of asymptotic stability and with norm bound for networked control system were presented by Lyapunov method and robust control theory. The simple design method of controller for networked control system with long time delay was proposed in terms of linear matrix inequalities. The simulation based on the networked control unstable inverted pendulum was studied. The simulation results show that the proposed method is feasible.
