摘　　要：研究基于网络控制离散时间Markov跳跃系统的H∞滤波问题。系统的输出信号通过受限的通信网络传输到滤波器,引入零阶保持器(ZOH),从网络中选择最新的数据。构造基于网络Markov跳跃离散系统,基于线性矩阵不等式,给出使滤波误差系统渐近稳定的充分条件以及H∞滤波器的设计方法。数值例子表明本方法的有效性。The problem of network-based H-infinity filtering for discrete-time Markov jumping systems was concerned.The output signals of the system under consideration were transmitted to the filter through a constraint communication network.By introducing a zero order holder(ZOH),the newest signal from the network was chosen to actuate the filter.Network-induced delays and packet dropouts were modeled as a Markov jumping linear systems.A sufficient condition of asymptotic stability for filtering error system was derived in terms of linear matrix inequality approach,and the design method of H-infinity filter was also given.A numerical example shows the effectiveness of the proposed approach.
