A novel variable structure control scheme for chaotic synchronization

This paper deals with synchronization problems of chaotic systems by applying a novel variable structure control (VSC) scheme. The synchronization of Chua’s circuit, the Rössler system and the Lorenz system, respectively, were used as illustrative examples. Simulation results indicated that the proposed new VSC scheme can significantly improve the synchronousness performance. These promising results justify the usefulness of the proposed controller in the application of secure communication.
