Chaos Synchronization in Complex Networks with Non-delay and Delay Couplings via Pinning Control

In the letter, we investigate the pinning synchronization in complex networks with non-delay and delay couplings. For the scheme of linear feedback control, synchronization criteria are obtained by Lyapunov stability theory. Sufficient conditions are derived for the synchronization to need the minimum number of pinning nodes. At last, a numerical simulation gives effectiveness of the pinning synchronization in complex networks with non-delay and delay couplings.
