四维系统中多涡卷混沌吸引子的仿真研究

Emulation of multi-scroll chaotic attractors in four-dimensional systems

通过构造一个新的非线性函数,研究一种新型四维系统多涡卷混沌信号发生器,这种多涡卷混沌信号发生器的主要特征是随着自然数n的增加,能产生2n+2个多涡卷混沌吸引子,通过改变控制参数k可以改变多涡卷混沌吸引子的混沌边界.并在EWB平台上设计了具体的电路,进行仿真实验验证.

A new type of four-dimensional chaotic system is studied by constructing a new nonlinear function. The characteristic of this chaotic systems is that the 2n ＋ 2 scroll chaotic attractors are found in our computer simulation with the natural number n increasing, and the bounds of the chaotic attractors is modified by changing the control parameter k. Finally, the circuit is designed and emulated on EWB platform.
