This paper proposes a new H, lag synchronization scheme for time-delayed chaotic systems with external disturbance. Based on Lyapunov-Krasovskii stability theory, the H lag synchronization controller is presented such that the time-delayed lag synchronization error system is asymptotically stable with a guaranteed H performance. It is shown that the design of the proposed lag synchronization controller can be achieved by solving a linear matrix inequality (LMI), which can be easily facilitated by using some standard numerical packages. The lag synchronization problem for time-delayed chaotic Hopfield neural networks is provided to demonstrate the effectiveness of the developed theoretical results.
