Outer Synchronization of Complex Networks with Nondelayed and Time-Varying Delayed Couplings via Pinning Control or Impulsive Control

Abstract EN

The outer synchronization problem between two complex networks with nondelayed and time-varying delayed couplings via two different control schemes, namely, pinning control and impulsive control, is considered.

Firstly, by applying pinning control to a fraction of the network nodes and using a suitable Lyapunov function, we obtain some new and useful synchronization criteria, which guarantee the outersynchronization between two complex networks.

Secondly, impulsive control is added to the nodes of corresponding response network.

Based on the generalized inequality about time-varying delayed different equation, the sufficient conditions for outer synchronization are derived.

Finally, some examples are presented to demonstrate the effectiveness and feasibility of the results obtained in this paper.
