| 摘 要： | 基于混沌吸引子周期轨道理论和电路仿真技术，分析了蔡氏混沌电路系统随元件参数值变化的动力学特性，给出了电路参数平面上的混沌区域图．根据该混沌区域图，找到了系统产生双涡卷混沌吸引子且容差范围为最大时的元件参数标称值，同时计算出了元件参数标称值的容差范围．文中还给出了电路参数值的选择算法步骤，以便为混沌振荡电路的硬件实现提供理论指导．

| Abstract: | First,the dynamic characteristics of the circuit system under the influence of various circuit parameters are analyzed on the basis of the periodic orbit theory about the chaotic attractor and by means of the circuit simulation technology,and the chaotic region diagram in the circuit parameter plane is presented.Next,the standard values of circuit parameters and the maximum possible parametric range when the circuit has 2-scroll attractors are calculated according to the presented chaotic region diagram.Finally,the steps of the algorithm in selecting the parameters of the Chua's circuit are proposed.All these provide theoretical guidance for the realization of the chaotic oscillatory circuit. |
