Synchronization stability in an array of linearly coupled connected neural networks with multiple delays

In this paper, synchronization stability problem for arrays of linearly coupled multiple delayed neural networks is studied on the basis of LMI method. The derived results greatly improve and generalize some earlier results. Some key problems between stability of recurrent neural networks and synchronization stability of arrays of coupled neural networks are discussed in some Remarks. A numerical example is used to illustrate the effectiveness of the derived results.
