In this paper, we propose a new H synchronization strategy, called a fuzzy delayed output feedback H synchronization (FDOFHS) strategy, for chaotic systems in the presence of external disturbance. Based on Lyapunov-Krasovskii theory, the T-S fuzzy model, and a delayed feedback control scheme, the FDOFHS controller can guarantee stable synchronization. Furthermore, this controller reduces the effect of external disturbance to an H norm constraint. The proposed controller can be obtained by solving the linear matrix inequality (LMI) problem. A simulation study is presented to demonstrate the validity of the proposed FDOFHS approach.
