Robust H/sub /spl infin// filter design for linear systems with state delay and parameter uncertainty

Abstract

This paper addresses the problem of robust H/sub /spl infin// filter design for linear systems with state delay and parameter uncertainty. The sufficient condition of the existence of the robust filter, such that, for all admissible uncertainties, the filtering process remains robustly stable and the transfer function meets the prescribed H/sub /spl infin//-norm upper-bound constraints, is derived by the modified Riccati inequalities. The filter is parameterized.
