Impulsive synchronization of coupled chaotic systems via adaptive-feedback approach

The issue of impulsive synchronization of adaptive-feedback coupled chaotic systems is investigated. We show the availability of the scheme by using the theory of the largest invariant set. Based on the stability analysis of impulsive differential equations, a sufficient criterion for the general case is derived. The scheme is applied to the famous Lorenz systems. The example illustrates faster convergence rate and smaller final coupling strength of the proposed scheme.
