Abstract:In this paper, the H∞ synchronization is intensively investigated for general delayed complex dynamical networks. The network under consideration contains unknown but bounded nonlinear coupling functions, timevarying delay, external distur bances, and Itôtype stochastic disturbances, which is a zeromean real scalar Wiener process. Based on the stochastic Lyapunov stability theory, Itô’s differential rule, and linear matrix inequality (LMI) optimization technique, some delaydependent H∞ synchro nization schemes are established, which guarantee robust stochas tically mean square asymptotically synchronization for drive net work and noiseperturbed response network as well as achieving a prescribed stochastic robust H∞ performance level. Finally, de tailed and satisfactory numerical results have validated the feasi bility and the correctness of the proposed techniques. 
Key words:delaydependent H∞ synchronization; general de layed complex networks with stochastic disturbances; linear ma trix inequality (LMI); mean square stability
