New criterion of exponential stability for uncertain systems with time-varying delay

This paper has studied the problem of the exponential stability for uncertain systems with time-varying delay. According to Wirtinger´s inequality method a new criteria is derived based on a linear matrix inequality and convex combination approach to dispose the time-delay in the derivative of Lyapunov-Krasovskii´s function. Finally, this paper has used several numerical examples, in order to illustrate effective results.
