摘要：AbstractThis paper considers the network synchronization problem of nonlinear systems with sampled-data couplings. In particular, we focus on sufficient conditions for full synchronization of systems interconnected via sampled-data couplings. We have already derived a sufficient condition for synchronization of two mutual coupled systems whose outputs are simultaneously measured with the same constant sampling interval. By extending the result, in this paper, we show that the network synchronization condition can be estimated from that of two coupled systems by scaling the stability region with a factor related to the eigenvalues of the graph Laplacian. Furthermore, we discuss the effect of asynchronous sampling on synchronization. The validity of the obtained results is illustrated by numerical simulations.
