This paper makes some great attempts to investigate the global exponential synchronizationfor arrays of coupled delayed Cohen-Grossberg neural networks with both delayed coupling and one singledelayed one. By resorting to free-weighting matrix and Kronecker product techniques, two novel synchronization criteria via linear matrix inequalities LMIs are presented based on convex combination, inwhich these conditions are heavily dependent on the bounds of both the delay and its derivative. Owingto that the addressed system can include some famous neural network models as the special cases, theproposed methods can extend and improve those earlier reported ones. The efficiency and applicabilityof the presented conditions can be demonstrated by two numerical examples with simulations.
