摘要
This work investigates the adaptive Q-S synchronization of non-identical chaotic systems with unknown parameters. The sufficient conditions for achieving Q-S synchronization of two different chaotic systems (including different dimensional systems) are derived, based on Lyapunov stability theory. By the adaptive control technique, the control laws and the corresponding parameter update laws are proposed such that the non-identical chaotic systems are to have Q-S synchronization. Finally, four illustrative numerical simulations are also given to demonstrate the effectiveness of the proposed scheme.
