摘　　要：对同时具有网络诱导时延和数据包丢失的网络控制系统进行了建模、稳定性分析和控制器的设计.网络诱导时延为小于一个采样周期的短时延,随机丢包过程是具有普遍意义的任意丢包过程,其数字特征不必先验得到,运用保证闭环网络控制系统渐近稳定的充分条件,得到了状态反馈控制器的设计方法.仿真结果证明了该方法的有效性.With the presence of network-induced delay and packet loss, network control system modeling, stability analysis and controller design are carried out. Because network-induced delay is less than a sampling period for a short time delay, random packet loss is a process universal significance of the arbitrary packet loss process, whose characteristics do not have priority to the figures Based on closed-loop network control system to ensure asymptotic stability of a sufficient condition, the design method of state feedback controller is obtained. Simulation results show the effectiveness of the method.
