Delay-dependent robust H/sub (infinity)/ control for uncertain time-delay systems

Robust stabilisability and H/sub (infinity)/ control criteria are provided for a class of uncertain time-delay systems with multiple state delays. Simpler and less conservative delay-dependent results given in terms of linear matrix inequalities (LMIs) are derived based on the Lyapunov-Krasovskii functional method and Riccati equation transformation technique
