摘　　要：研究了具有时延和数据包丢失的网络控制系统H∞状态反馈控制问题.考虑了网络控制系统中同时存在时延和数据包丢失的情况,将丢包过程建模为有限状态的马尔可夫过程.在此模型的基础上,利用Lyapunov稳定性理论和线性矩阵不等式方法,给出了保持系统均方稳定且满足H∞性能的控制器存在的充分条件,并给出了相应的设计方法.最后数例仿真结果表明了控制器设计方法的有效性.The H∞ state feedback control problem of networked control system（NCS） with time-delay and data packet dropout is studied. Time-delay and the data packet dropout are both considered in networked control system and the data packet dropout is modeled as finte state Markovian process. Based on this model, the sufficient conditions for the existence of controller, which guarantee the mean-square stability of NCS and meet the H∞ performance, are given via Lyapunov stability theory and linear matrix inequality technique. The corresponding controller desgin techniques are also provided. Finally, the simulation results of numerical example show the effectiveness of the method.
