摘要：

This paper is involved with the adaptive modified function projective synchronization (MPS) problem of hyperchaotic systems with unknown parameters Based on the Lyapunov stability theorem and adaptive control method, adaptive controllers and parameters update laws can be presented for the MFPS not only between two identical hyperchaotic systems but particularly also between two different hyperchaotic systems with fully unknown or partially unknown parameters. Moreover, the coupling strength can be automatically adapted to a updated law Numerical simulations are presented to show the effectiveness of the proposed synchronization schemes (C) 2009 Elsevier B.V.
