Robust synchronization of dynamical network with impulsive disturbances and uncertain parameters

摘要

In this paper, we investigate robust global exponential synchronization of an impulsive complex dynamical network with uncertain parameters. The new impulse proposed is added on the coupled states and is relative not only with the coupled states at the current impulsive time instants but also with ones at the previous impulsive time instants. Some sufficient conditions are derived to ensure robust exponential synchronization of the presented impulsive dynamical network by using the stability analysis for impulsive delay systems. The obtained results extend the existed ones. A numerical example is finally exploited to show the effectiveness of the obtained results.
