多涡漩蔡氏电路的计算机辅助设计优化

Computer-aided Optimized Design of Multi-vortex Chua's Circuit

首先给出通用设计方法设计出来的蔡氏电路,其次分析其中的单运放限幅式静态非线性电路结构,提出多运放静态非线性电路设计方法,从单运放开始逐渐增加运放个数的电路结构并逐级验证对应多涡漩蔡氏电路混沌特性.之后介绍阶跃式静态非线性电路结构.突出设计将三次方曲线修改为任意次方拓扑曲线.主要叙述电路优化设计方法.最后使用EWB仿真并给出其结果.

Chua＇s circuit design using universal design method is given firstly in this paper,it followed by analysis of the single op amp clipping static non-linear circuit,multiple op-amps static non-linear circuit design is presented,starting from single op-amp gradual increasing in number of op-amp circuit and sequential verify the chaotic charactoristics of corresponding multi-vortex Chua＇s circuit.The Stepped static non-linear circuit is introduced,the design of revised cubic curve as arbitrary cubic curve topology is highlighted.The circuit design optimizational methods are described.Simnlation using EWB are given.Finally EWB simulation and its results.
