Abstract
A new 4-D hyperchaotic two-wing system with three quadratic nonlinearities is
proposed in this paper. The dynamical properties of the new hyperchaotic system are described
in terms of phase portraits, Lyapunov exponents, Kaplan-Yorke dimension, symmetry,
dissipativity, etc. Also, a detailed dynamical bifurcation analysis of the hyperchaotic system
has been studied using bifurcation diagrams. As an engineering application, an electronic
circuit realization of the new hyperchaotic two-wing system is developed in MultiSIM, which
confirms the feasibility of the theoretical hyperchaotic two-wing system.
Keywords: 4-D hyperchaotic, three quadratic, nonlinearities
