| 摘 要： | 针对具有随机时延和丢包情况的网络控制系统,考虑被控对象存在建模误差和外界未知干扰,利用Lyapunov稳定性理论和线性矩阵不等式方法(LMI),给出当网络传输中发生丢包时,网络闭环控制系统渐近稳定的充分条件,并通过求解LMI组的方式得到状态反馈控制器的设计结果.仿真结果验证了本文方法的有效性.

| Abstract: | The problem of robust controller design of Networked Control Systems(NCSs)with uncertain parameters and fixed networked-induced delays is studied in this paper.Firstly,the model of closed-loop NCSs with random data packets dropout is obtained.Then,the sufficient condition of the system stability is presented by solving a set of linear matrix inequalities.Finally,a simulation example is given to illustrate the validity of the proposed method. |
