LMI approach to robust H∞ filtering for neutral delay differential systems

摘要

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