| 摘 要： | 针对一类混沌系统,提出一种以部分状态变量作为发射信号的混沌系统全局指数同步方法.该方法结合微分方程的稳定性理论,将驱动系统和响应系统的误差系统分成不同的2个部分,理论证明以该方法达到整体指数同步需要的条件.利用该方法,通过对一类金融混沌系统和陈氏混沌系统的数值仿真验证了该方法的有效性.

| Abstract: | This paper proposes a global exponential synchronization method for a kind of chaotic system with partial state variables as transmission signal. This method is combined with the stability theory of differential equation, and it separates the error system between driving-system and response-system into two different parts. Theoretical analysis shows that this method has achieved the necessary condition of global exponential synchronization. And the method has been proved to be effective by the numerical simulation of a kind of financial chaotic system and Chen chaotic system. |
