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 <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">γcos(ωt)</i> . 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.
