A general scheme for Q-S synchronization of chaotic systems

This paper addresses the Q-S synchronization between chaotic and/or hyper-chaotic systems. Based on the Lyapunov stability theorem, a general scheme for Q-S synchronization of chaotic and/or hyper-chaotic systems is proposed. The drive and response systems discussed in this paper can be strictly different dynamical systems (including different dimensional systems). Four illustrative numerical simulations are also given to demonstrate the effectiveness of the proposed general scheme for Q-S synchronization.
