Impulsive synchronization of a nonlinear coupled complex network with a delay node

We investigate the impulsive synchronization of a nonlinear coupled complex network with a delay node.Both delay coupling and non-delay coupling,as well as the symmetrical coupling matrix and the asymmetrical coupling matrix are considered.Based on the comparison theorem of an impulsive differential system,some novel synchronization criteria are derived.Finally,numerical simulations demonstrate the effectiveness of the proposed synchronization criteria.
