Robust H_∞Control Design of Uncertain Time-delay Systems with Input Delay

The problem of robust ?∞ state feedback control design for a class of uncertain systems with two different time delays in the state is investigated in this paper. The main feature of the paper is to develop a delay-dependent ?∞ controller, which ensures robust asymptotic stability of the system as well as a desired ?∞ performance. By constructing a Lyapunov-Krasovskii function, some delay-dependent sufficient conditions for the existence of the ?∞ state feedback controller is derived in terms of linear matrix inequalities. A numerical example is provided to illustrate the effectiveness of the proposed method.
