Robust H∞ Filtering for Neutral Delay Systems

This paper focuses on the problem of robust H_infin filtering for neutral delay systems with norm-bounded parameter uncertainty. The problem we address is to design a Leunberger type filter such that the resultant error system is asymptotically stable and the effect of the noise on the estimation error is attenuated to a prescribed level. Sufficient conditions for the solvability of the robust H_infin filtering problem are obtained in terms of LMIs. A Leunberger type filter is constructed by the LMIs. A numerical example is given to illustrate effectiveness of the proposed algorithm
