摘要：

This paper is concerned with the neutral-delay-dependent and discrete-delay-dependent stability for uncertain neutral systems with mixed delays and norm-bounded uncertainties. Through constructing a new augmented Lyapunov-Krasovskii functional and proving its positive definiteness, introducing some slack matrices and using integral inequality, the improved delay-dependent stability criteria are derived in terms of linear matrix inequalities. Numerical examples are given to illustrate the significant improvement on the conservatism of the delay bound over some existing results.
