Generalized synchronization of bidirectionally coupled chaos systems

Abstract

The conditional entropy is used to assess the generalized synchronization of bidirectionally coupled chaotic systems. By increasing the coupled strength, the generalized synchronization appears when there is a sharp minimum of the conditional entropy. We apply this criteria to the case of the coupled Rssler-Lorenz an d Rssler-Rssler system to test our method. Numerical results show that it is very effective and robust.
