Projective Synchronization in Drive--Response Networks via Impulsive Control

Impulsive projective synchronization in 1+N coupled chaotic systems are investigated with the drive--response dynamical network (DRDN) model. Based on impulsive stability theory, some simple but less conservative criteria are achieved for projective synchronization in DRDNs. Furthermore, impulsive pinning scheme is also adopted to direct the scaling factor onto the desired value. Numerical simulations on generalized chaotic unified system are illustrated to verify the theoretical results.
