文章研究了两个具有相同参数与不同参数的离散混沌动力学系统的同步问题,并在反馈控制下成功地实现了两个Logistic系统的同步和广义同步。特别是,在两个不同的混沌动力学系统间,实现了驱动系统的动力学行为由混沌转为周期,由周期转为混沌,以及由混沌转为另一混沌行为的控制。通过仿真实验,在两个相同与不同的Logistic系统间分别实现了三种混沌同步现象(严格同步、事实同步和基本同步)。
In this paper, the synchronization problems of two discrete chaotic systems with the same parameters and different parameters are studied. The synchronization and generalized synchronization of two Logistic systems are successfully realized under the feedback control. Especially, between two different chaotic dynamical systems, the dynamic behavior of the drive system is changed from chaos to period, from period to chaos, and from chaos to chaos. Through simulation experiments, three kinds of chaotic synchronization (strict synchronization, factual synchronization and basic synchronization) are implemented respectively between two identical and different Logistic systems.
