On Synchronization of Two Identical Novel Hyperchaotic Systems with Fully Unknown Parameters

摘要

This paper concerns the synchronization problem two identical novel hyperchaotic systems with fully unknown parameters. A novel adaptive synchronization controller is realized for the response system to asymptotically synchronize two identical novel hyperchaotic systems. The asymptotic stability of the synchronization error system is guaranteed based on the Lyapunov stability theory and adaptive control idea. The effectiveness of the proposed adaptive synchronization method is verified by simulation studies.
