A New 4D Four-wing Hyperchaotic Attractor and Its Circuit Implementation

摘要

In this paper, a new simple four-dimensional continuous-time autonomous hyperchaotic system is introduced, which displays a complicated four-wing attractor. The existence of the hyperchaos is verified by bifurcation analysis, and in the meantime bifurcation routes from period to quasi-period, then to chaos and finally to hyperchaos is determined. Different configurations of the hyperchaotic attractor are illustrated not only by computer simulation but also by electronic circuit realization.
