| 摘 要： | 对一类严格交叉反馈超混沌系统的混沌同步进行了讨论。基于有限时间稳定性理论设计了反馈控制器和参数更新定律,通过分步设计控制器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。数值仿真结果表明,驱动系统和响应系统在有限时间内是同步的,未知参数能在有限时间内被识别,且未知参数越大,系统收敛的速度越快。

| Abstract: | This paper deals with the finite-time chaos synchronization of cross-strict feedback hyperchaotic system.Based on the finite-time stability theory,the control law and the parameter update law are proposed to realize finite-time chaos synchronization of cross-strict feedback hyperchaotic system under partial unknown parameters.The controller is simple and robust to noise.Numerical simulations are given to show the effectiveness of the proposed controller. |
