Adaptive synchronization of hyperchaotic Chen system with uncertain parameters

摘要

This article addresses control for the chaos synchronization of hyperchaotic Chen system with five uncertain parameters. Based on the Lyapunov stability theory, an adaptive control law is derived to make the states of two identical hyperchaotic Chen systems asymptotically synchronized. Finally, a numerical simulations is presented to show the effectiveness of the proposed chaos synchronization scheme. (c) 2005 Elsevier Ltd. All rights reserved.
