Sliding mode controller design for chaos synchronization of Rikitake chaotic systems

In this paper, synchronization of Rikitake chaotic systems and its application in secure communication are presented. Sliding mode control is using scheme to solve the synchronization problem of Rikitake chaotic systems. The proposed scheme guarantees the synchronization between the master and slave Rikitake chaotic systems based on the use of Lyapunov stability theory. Moreover, the selection of switching surface and the existence of sliding mode is addressed. Finally, the experimental results validate the proposed chaotic synchronization approach.
