摘要
通过四维系统中的多涡卷混沌吸引子的研究,提出了一个简便数学公式来确定产生多涡卷的分段线性伏安特性的转折点电压,该方法可产生任意个数的涡卷。介绍了以此方法确定了产生6-8涡卷的混沌振荡电路,并对6-8涡卷的混沌振荡电路进行了仿真。最后用脉冲同步法对5涡卷混沌振荡电路进行了同步仿真研究。
A simple formulas is presented for determining the turning point voltages, which give rise to multi-scroll chaotic attractors, of a piecewise linear A-V characteristic. The proposed method can be used to generating attractors having any scrolls. Accordingly, parameters of chaotic oscillator capable of producing 6-8 scrolls are determined. Associate simulation is conducted for 6-8 scroll chaotic attractors. Finally synchronization simulation of 5 scroll chaotic oscillator is investigated using impulsive synchronization.
