摘要
经典的蔡氏电路是一个简单混沌电路,能够产生丰富的混沌现象,然而该电路的系统参数基本上是固定的,不同混沌电路之间的电路不具备通用性。基于此,提出在Multisim软件上通过模块化的设计方法重构蔡氏混沌电路,所有电路参数均独立可调,着重介绍了如何用二极管及运算放大器实现复杂的非线性函数,并给出了蔡氏混沌电路相应的双涡卷吸引子仿真结果。
The classic Chua chaos circuit is very simple circuit which is capable of generating the chaotic signals. However its parameters of the circuit is essentially fixed, and do not have versatility between different chaotic circuits. It provides the reconstruction of Chua＇s chaotic circuit by method of modular design based on Multisim software. All parameters of Chua chaos circuit can be adjusted independently. And it is emphasis on how to use diodes and an operational amplifiers to achieve the absolute value circuit of complex nonlinear function, the simulation results of the Chua circuit double scroll attractors is given correspondingly.
