Abstract

This paper is concerned with the problems of H∞ filtering for discrete-time systems with time-invariant delay. The recent developed parameter-dependent Lyapunov function (PDLF) method is exploited and an slack variable with an particular structure is introduced. As a consequence, sufficient convex linear matrix inequality (LMI) condition is derived to solve the H∞ filter design problem. A numerical example is given to illustrate the effectiveness of the proposed methods.
