摘要：
In this paper, an approach of adaptive synchronization and parameters identification of hyperchaotic systems with linearly dependent uncertain parameters 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 hyperchaotic systems, with all the linear dependent system parameters unknown, can be achieved simultaneously. Theoretical proof and numerical simulation with Rossler hyperchaotic system demonstrate the effectiveness and feasibility of the proposed technique. (c) 2005 Elsevier Ltd. All rights reserved.
