Graph-theoretic method on exponential synchronization of stochastic coupled networks with Markovian switching

In this paper, the issue of exponential synchronization for a class of stochastic coupled networks with Markovian switching is investigated. Based on some results in graph theory, Lyapunov stability theory and state feedback control technique, several sufficient criteria have been derived to ensure the pth moment exponential stability and almost sure exponential stability for the error network. That is, under these sufficient criteria, drive-response coupled networks can be pth moment exponentially synchronized and almost surely exponentially synchronized, respectively. Finally, stochastic Cohen-Grossberg neural networks with Markovian switching is employed to illustrate our feasible results.
