Robust H/spl infin/ Filtering for Uncertain Linear Neutral Delay Systems

This paper deals with the H_infin filtering problem for uncertain linear neutral delay systems. An algebraic Riccati matrix inequality approach is proposed to design a robust H_infin filter such that filtering systems remains asymptotically stable and satisfies a prescribed H_infin; performance level for all admissible uncertainties. We establish the conditions under which the desired robust H_infin filter exist, and derive the explicit expression of these filters. A numerical example is provided to illustrate the effectiveness of proposed design approach
