摘要
In this paper, the problem of delay-dependent stability for uncertain neutral systems with time-varying delays is considered. The parameter uncertainties are assumed to be norm-bounded. By constructing an augmented Lyapunov functionals, a novel delay-dependent stability criterion for the system is established in terms of LMIs (linear matrix inequalities). Six numerical examples are given to show the effectiveness of proposed method. (C) 2008 Elsevier Inc. All rights reserved.
