三维增广Lü系统的实验验证

Experimental Verification of Three-Dimensional Chaotic Augmented Lü System

笔者采用模拟电路设计了一个硬件实验电路,验证了三维混沌增广Lü系统可产生复杂的混沌信号。通过一组拨位开关的转换,改变系统代数方程组表达式中常数控制项的数值,可以观察到混沌增广Lü系统既能产生两个共存的双涡卷混沌上吸引子和下吸引子,也可以实现单双涡卷混沌吸引子的转换、上下混沌吸引子的连接以及上下混沌吸引子的转换。

An analog circuit is designed bt the writers to verify that the three-dimensional chaotic augmented Lü system can generate complex chaotic signal. By setting the status of a digital switch set, the parameters of constant control terms of system equations can be set to show that chaotic augmented Lü system can not only generate two co-existing double-scroll chaotic upper-attractor and lower-attractor, but also realize the transformation of single-scroll and double-scroll chaotic attractor, the connection of the chaotic upper- attractor and lower-attractor, and the transformation of chaotic upper-attractor and lower-attractor.
