New results on synchronization for complex dynamical networks with time-varying coupling delay and sampled-data

This paper is concerned with the synchronization problem for complex dynamical networks with time-varying coupling delay and sampled-data. The sampling period considered here is assumed to be time-varying but bounded. A novel exponential synchronization condition is established based on the Gronwall´s inequality, and an explicit expression for a set of sampled-data synchronization controllers is also given in terms of the solution to linear matrix inequalities. A numerical example is introduced to show the effectiveness of the given result.
