摘要: 本文对一类网络环境下的离散线性系统进行了可靠性滤波器设计,其中用一组随机变量来表示传感器的概率性失真,并综合考虑网络环境的时滞、错序、丢包等非理想服务质量,建立了包含传感器随机失真的系统模型;通过使用李亚普诺夫泛函稳定性理论和线性矩阵不等式技术给出了可靠性滤波器设计算法存在可行解的充分性条件,最后通过数值算例验证本文给出方法的有效性.

Abstract: In this paper,the network-based reliable filtering is investigated for a class of discrete linear systems.The faults of sensors occur randomly and the failure rates are governed by some stochastic variables.A new model is provided under consideration of the network-induced delay,the data packet dropout,the wrong sequences in the transmission,and random sensor failure.By using the Lyapunov stability theory and the linear matrix inequalities techniques,sufficient criteria are derived for the existence of a solution to the algorithm of reliable filtering.Final,an example is exploited to illustrate the effectiveness of the proposed method.

Key words: reliable control, filtes design, network control systems, stochastic failure rates, non-ideal network quality
