摘　　要：主要选取了四个三维自治混沌系统,通过理论计算与MATLAB数值仿真,研究四个混沌系统的基本动力学特征。通过三种不同组合方式来进行驱动-响应的异结构组合同步,采用反同步方法设计单个控制器,可以控制四个混沌系统在不同的组合方式时均能达到反同步。用Multisim软件搭建硬件电路模型,验证系统与同步的有效性。此设计因为系统较多且组合方式不定,在保密通信方向有一定的应用价值。In this paper,four three-dimensional autonomous chaotic systems are selected.Through theoretical calculation and MATLAB numerical simulation,the basic dynamic characteristics of the four chaotic systems are studied.By using three different combination methods to synchronize the different structure of drive-response,a single controller designed by anti-synchronization method can control the four chaotic systems in different combination methods to achieve anti-synchronization.The hardware circuit model is built with Multisim software to verify the validity of the system and synchronization.This design has certain application value in the direction of secure communication because there are many systems and the combination mode is uncertain.
