| Abstract: | In this paper, the problem of robust control for uncertain neutral systems with time-varying delays is considered. The time delay is supposed to be unknown and time-varying. Based on Lyapunov-Krasovskii functional theory, delay-dependent criteria for the existence of state feedback controllers are proposed, which ensures robust stabilization and disturbance attenuation of the systems. Linear matrix inequality （LMI） approach is used to solve the robust control problem. At last, a numerical example is illustrated to prove the usefulness of the proposed results. |
