不确定参数网络控制系统鲁棒控制器设计

Robust Controller Design of Network Controll Systems with Uncertain Parameters

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.

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 drop- out 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.
