Finite-time synchronization of coupled Cohen-Grossberg neural networks with time-varying delays

This paper is concerned with finite-time synchronization for two models of coupled Cohen-Grossberg neural networks with time-varying delays. In the first one, linearly coupled Cohen-Grossberg neural networks is considered. In the second one, nonlinearly coupled Cohen-Grossberg neural networks is discussed. Based on finite-time stability theory, some inequality techniques, and designed controllers, some criteria which make the coupled Cohen-Grossberg neural networks with linear coupling and nonlinear coupling realize synchronization are derived respectively. Furthermore, the settling times of synchronization are also estimated. Finally, a numerical example is given to confirm the effectiveness of the proposed results.
