摘要：
This letter presents chaos synchronization problem of two different hyperchaotic systems when the parameters of drive and response systems are fully unknown or uncertain. Based on Lyapunov stability theory, all adaptive control law and a parameter update rule for unknown parameters arc derived such that two different high dimensional chaotic systems arc to be synchronized. Hyperchaotic Chen system and Second-harmonic generation (SHG) system are taken as an illustrative example to show the effectiveness of the proposed method. (c) 2007 Elsevier Ltd. All rights reserved.
