摘要
基于控制李亚普洛夫函数(CLF)和有限时间稳定性理论,设计了反馈控制器和参数更新定律,实现了参数未知下的严格交叉超混沌系统的有限时间混沌同步,在同步的过程中,未知参数也被识别,数值仿真结果显示所提出方法的有效性.
This paper deals with the finite--time chaos synchronization of cross--strict feedback hyperchaotic system. Based on the control Lyapunov function （CLF） and the finite--time stability theory, the controller and the parameter renewal law are proposed to realize finite--time chaos synchronization of cross--strict feedback hyperchaotie system under partial unknown parameters. Numerical simulations are given to show the effectiveness of the proposed controller.
