摘　　要：研究两个线性参数不确定的Liu混沌系统的自适应同步现象,找出了自适应的控制器和参数辨识结构,借助Lyapunov稳定性理论,探讨了线性参数不确定的混沌系统产生自适应同步所需的充分条件,数值仿真结果表明提出的控制方案是可行的,且同步的连度好.The adaptive synchronization of two Liu chaotic systems based on uncertaint linear parameter was studied.An adaptive controller and a parameter identifiable structure were found.The sufficient conditions for adaptive synchronization of chaotic systems with uncertain linear parameters were discussed by using the Lyapunov stability theory.The numerical simulation results showed that the control scheme is feasible,and its synchronous speed is better.

关 键 词：LIU混沌系统 混沌吸引子 线性参数不确定 自适应同步
