Further results on robust stability of neutral time-delay systems using Wirtinger-based inequality

This paper investigates the problem of robust delay-dependent stability analysis of uncertain neutral delay systems. Based on a new approach which suggests very closed lower bound of Jensen´s inequality by the use of Wirtinger inequality, an extended inequality is proposed. Moreover, by considering norm bounded uncertainties in system matrices, a robust stability criterion of uncertain neutral delay systems is studied. Two numerical examples are given to describe the less conservatism of the proposed methods.
