Delay-Dependent Stability for Time-Delay Systems with Nonlinear Perturbations

We study the stability of a class of time-delay systems with nonlinear perturbations. A new delay-dependent stability condition which can deal with arbitrarily time-varying delays is formulated by constituting a Lyapunov-Krasovskii functional, the result has less conservatism than those presented before. Numerical examples are presented to indicate significant improvements over some existing results.
