Abstract

Global exponential stability problem of the fuzzy Cohen-Grossberg neural networks (FCGNNs) with time-varying delay is considered in this paper. By using the Lyapunov-Krasovskii method, the novel sufficient conditions are obtained to guarantee the global exponential stability of the considered system. These conditions are expressed in the terms of linear matrix inequalities (LMIs), and can be checked by resorting to the Matlab LMI Toolbox. Finally, a numerical example is given to show the effectiveness of the obtained results.
