Synchronization of chaotic neural networks with mixed time delays

摘要

In this paper, we investigate the synchronization problems of chaotic neural networks with mixed time delays. We first establish the sufficient conditions for synchronization of iden-tical chaotic neural networks with mixed time delays via linear output feedback control. To overcome the difficulty that complete synchronization between nonidentical chaotic neu-ral networks cannot be achieved only by utilizing output feedback control, we use a sliding mode control approach to study the synchronization of nonidentical chaotic neural net-works with mixed time delays, where the parameters and functions are mismatched. Numerical simulations are carried out to illustrate the main results.
