Generating Hyperchaos via a Simple Periodic Forcing Signal*

Very recently, a new method of generating hyperchaos via a simple periodic forcing signal was introduced and a new hyperchaotic system was formulated by controlling a three-dimensional autonomous Chen chaotic system with a periodic driving signal γcos(ωt). The hyperchaotic attractor is not only verified with bifurcation analysis but also demonstrated by computer simulations. In this paper, we further investigate its bifurcation behaviors and electronic circuit implementation. A good qualitative agreement between the simulation and the experimental results is observed.
