Exponential lag synchronization of fuzzy cellular neural networks with time-varying delays

In this paper, we are concerned with the lag synchronization problem of fuzzy cellular neural networks (FCNNs) with time-varying delays. Some sufficient conditions on the exponential lag synchronization of the FCNNs are obtained using a nonlinear measure method. The exponential decay rate of synchronization error is estimated. We also show how to determine the controller gain matrix under this method. Finally, simulation examples are given to illustrate the effectiveness of our obtained results.
