Chen氏混沌电路实现与同步控制实验研究

Research on circuitry realization and synchronization of Chen chaotic systems

对Chen氏混沌系统的电路实现作了进一步的研究 ,推导出切实可行的电路参数 .在此基础上利用ElectronicWorkbench电路仿真软件进行了仿真实验 ,并搭建实现了实际的Chen氏电路 ,在示波器上观察到了Chen氏混沌系统的混沌波形 .同时 ,利用单变量耦合反馈控制方法对两个Chen氏系统的同步控制进行了实验研究 。

Based on the work in Int. J. of Bifurcation and Chaos vol.12(2002)1423,we address the circuitry realization problem of Chen chaotic system.We derive available circuit parameters with which we simulate the circuit on the simulation software Electronic Workbench.After realizing the Chen system in the circuit,we observe the chaotic figure on the oscillograph.Employing the synchroniation method using single variable coupling feedback,we conduct the synchronization experiments and obtain the parameter range for controlling the synchronization between two Chen's systems.
