Delay-dependent robust stability of time delay systems with Polytopic-Type uncertainty

S. Idrissi, E. H. Tissir, I. Boumhidi, N. Chaibi

Abstract



This paper presents a new delay dependent robust stability conditions for linear system with a time-varying delay and polytopic-type uncertainties based on Finsler's lemma and Lyapunov–Krasovskii functional. These conditions, expressed as a set of linear matrix inequalities, require no matrix variable to be fixed for the entire uncertainty polytope, which produces a less conservative stability test result. Numerical examples demonstrate the validity and effectiveness of the proposed criteria.

Keywords


Delay dependent conditions, robust stability, polytopic type uncertainties.
