Master-Slave Synchronization of 4D Hyperchaotic Rabinovich Systems

Abstract EN

This paper is concerned with master-slave synchronization of 4D hyperchaotic Rabinovich systems.

Compared with some existing papers, this paper has two contributions.

The first contribution is that the nonlinear terms of error systems remained which inherit nonlinear features from master and slave 4D hyperchaotic Rabinovich systems, rather than discarding nonlinear features of original hyperchaotic Rabinovich systems and eliminating those nonlinear terms to derive linear error systems as the control methods in some existing papers.

The second contribution is that the synchronization criteria of this paper are global rather than local synchronization results in some existing papers.

In addition, those synchronization criteria and control methods for 4D hyperchaotic Rabinovich systems are extended to investigate the synchronization of 3D chaotic Rabinovich systems.

The effectiveness of synchronization criteria is illustrated by three simulation examples.
