摘要
混沌序列是非线性方程描述的确定系统所产生的介于周期振荡与噪声之间的一种复杂振荡序列.蔡氏电路是一个经典,且简单的三阶自治系统,能够产生丰富的混沌现象。在对蔡氏电路进行数学建模的基础上,采用MultiSIM仿真软件对其进行仿真,并分析其产生的混沌信号的功率谱,从而找出一个最佳的电路参数,得到一个最好的,可用的混沌序列。
Chaotic sequence is a kind of complicated oscillation sequence,and lies between cycle oscillation and noise.Chua＇s circuit is a classic and simple system,which could produce abundant chaotic phenomenon.Based on its modeling,Chua＇s circuit is simulated with MultiSIM,and the power spectrum of chaotic signal is analyzed,thus a best circuit parameter is found and a most applicable chaotic sequence is obtained.
