A linear matrix inequality approach to the robust H∞ control problem of uncertain continuous- and discrete-time time-invariant systems with time delay in state vector input is developed. The main results provide sufficient delay-dependent conditions for problem, where explicit size plays a crucial role closed-loop stability. solutions that are found less conservative when compared other approaches recent literature.
