摘　　要：针对现实网络在数据传输中存在数据丢包和噪声干扰的特点,研究输出耦合离散时间复杂网络的鲁棒保性能状态估计问题,旨在减小数据丢包和噪声干扰对状态估计的影响。估计误差在满足均方指数收敛的前提下,能进一步满足一定的性能指标。利用Lyapunov稳定性理论与随机分析方法,以线性矩阵不等式的形式提出了鲁棒保性能状态估计增益矩阵存在的条件和设计准则。通过仿真表明,鲁棒保性能状态估计器可以有效地估计复杂网络的状态。In view of the data transmission characteristics of missing measurements and noise in the real network, this paper is concerned with the problem of robust guaranteed cost state estimation for coupled output discrete-time complex networks to reduce missing measurements and noise influence on state estimation. The estimation error dynamics is exponentially mean-square stable and the robust guaranteed cost performance requirement is satisfied. By using Lyapunov stability theory combined with stochastic analysis, an existence condition of the gain matrix and the relevant design criteria are proposed in the form of linear matrix inequalities （LMIs） for the robust guaranteed cost state estimation. Finally, a numerical simulation example is provided to demonstrate the effectiveness and the applicability of the proposed design approach.
