Adaptive impulsive observer for outer synchronization of delayed complex dynamical networks with output coupling

The synchronization problem of two delayed complex dynamical networks with output coupling is investigated by using impulsive hybrid control schemes,where only scalar signals need to be transmitted from the drive network to the response one. based on the lyapunov stability theorem and the impulsive hybrid control method,some sufficient conditions guaranteeing synchronization of such complex networks are established for both the cases of coupling delay and node delay are considered,respectively. finally,two illustrative examples with numerical simulations are given to show the feasibility and efficiency of theoretical results. © 2014 song zheng.
