A Novel Four-Dimensional Hyperchaotic System and Its Analysis
Gao Zhi-zhong · Journal of Wuhan University · 2011
In order to generate more complex hyperchaotic signals for chaotic information engineering,a new four-dimensional hyperchaotic system is built in the paper.Some of its basic dynamical properties,such as the feature of equilibrium,the attractors,the time response,the power spectrum,the bifurcation diagram and the Lyapunov exponent spectrum,are studied in detail by means of theoretical analysis and numerical simulation.Results show that the new system's dynamics behavior can be periodic,quasi-periodic,chaotic and hyperchaotic as the typical parameter varies.
