H∞ Filter Design for Discrete Networked System with Random Delay
摘要
Abstract
By constructing a new filtering-error system, this paper is deals with the problem of filter design for discrete-time networked systems with stochastic communication delays. It is assumed that the delay distribution information of the previous h steps is known, respectively, while the delay information of step h + 1 to the upper bound is known as a whole, then a new filtering-error system model is constructed by introducing a sequence of random variables. During the process of stability analysis and filter design,by introducing the free weighting matrix and using the convexity property of the matrix inequality, conservative criteria are reduced in terms of analyzing the feasibility of a set of linear matrix inequalities ( LMIs ). Moreover, when we get more delay information of step h,the corresponding stability criteria can be improved. Simulation examples demonstrate the effectiveness and the merit of the proposed filter design technique in this paper.关键词
