Adaptive synchronization of uncertain Rossler hyperchaotic system based on parameter identification

In this Letter, an approach of adaptive synchronization and parameters identification of uncertain Rossler hyperchaotic system is proposed. The suggested tool proves to be globally and asymptotically stable by means of Lyapunov method. With this new and effective method, parameters identification and synchronization of Rossler hyperchaotic with all the system parameters unknown, can be achieved simultaneously. Theoretical proof and numerical simulation demonstrate the effectiveness and feasibility of the proposed technique. (C) 2003 Elsevier B.V All rights reserved.
