摘　　要：针对不确定的网络控制系统存在随机丢包和外部扰动信号等问题,设计一类H_(∞)滤波器,以提高控制系统鲁棒性.运用随机伯努利序列刻画传感器测量数据包丢失的数学模型,将滤波误差系统构建为含有随机不确定参数的闭环系统.通过Lyapunov函数和概率论推导出滤波误差系统稳定性条件,并给出滤波器参数矩阵求解的方法.仿真示例表明所设计H_(∞)滤波器的可行性.In order to improve the robustness of uncertain network control systems,a class of H_(∞)filter was designed to solve the problems of random packet dropouts and external interference signals.The mathematical model of sensor measurement packet dropouts was described by random Bernoulli sequence and the filtering error systems were constructed as a closed-loop systems with random uncertain parameters.The stability condition of filtering error systems were derived by Lyapunov function and probability theory,and the method of solving filter parameter matrix was also given.The feasibility of the designed H_(∞)filter was demonstrated by a simulation example.
