LMI approach to robust H-infinity filtering for neutral delay differential systems

Abstract

In this paper, we investigate the problems of stability and H-infinity filtering for a class of linear neutral delay-differential systems. A linear matrix inequality approach is proposed to design a robust H-infinity. filter such that the filtering system remains asymptotically stable and the bound of H-infinity. norm is minimized. The Lyapunov stability theory is used for analysis of the system. A numerical example illustrate the theoretical results. (C) 2003 Elsevier Inc. All rights reserved.
