Delay-dependent stability criteria for uncertain neutral systems

In this paper, the problem of delay-dependent stability criteria for a class of constant time-delay neutral systems with time-varying structured uncertainties is investigated. By using Lyapunov-Krasovskii functional that splits the whole delay interval into two subintervals and defines different Lyapunov function on each subinterval. The asymptotic stability criteria and robustly stability criteria are presented in terms of strict linear matrix inequalities (LMIs). Two numerical examples are given to indicate that the results presented in this paper are effective and less conservative than some existing results.
