Free-weighting Matrices Approach to H ∞ Filtering for a Class of Uncertain Linear Systems with Time-varying Delay

摘要：

This paper investigates the problem of delay-dependent robust H∞ filtering for uncertain linear systems with time-varying delay. Given a stable system with parameter uncertainties residing in a polytope with s vertices, the focus is on designing a robust H∞ filter such that the filtering error system is robustly asymptotically stable with a prescribed H∞ noise attenuation level. The main technique used is the free-weighting matrix method by considering the additional useful terms. As a result, an improved linear matrix inequality-based delay-dependent stability criterion is obtained, which is less conservative. Finally, two examples have been presented to illustrate the effectiveness of the proposed methodology.
