Exponential stability and periodic solutions of FCNNs with variable coefficients and time-varying delays

In this paper, we investigate the fuzzy cellular neural networks (FCNNs) with variable coefficients and time-varying delays. A series of simple sufficient conditions is obtained for checking the boundedness, global exponential stability and the existence and global exponential stability of periodic solutions of FCNNs with variable coefficients and time-varying delays by using Young inequality and general Lyapunov functional. The results given in this paper extend and improve the earlier publications.
