A Generation of Strong Hyperchaos from A Three-dimensional Autonomous Smooth Chaotic System
This paper proposes a new four-dimensional hyperchaofic system constructed based on a modified three-dimensional chaotic system by adding a simple nonlinear state feedback controller. The complex dynamical behaviors of this hyperchaotic system are further investigated, including basic properties, Lyapunov exponents spectrum, bifurcation analysis, Poincare sections. The system can evolve into periodic, quasiperiodic, chaotic and hyperchaotic attractors, moreover, when this new system is hyperchaotic, its two positive Lyapunov exponents are much larger than those of hyperchaotic systems already reported. Under appropriate parameter conditions, the largest Lyapunov exponent can reach 26, and the second positive Lyapunov exponent can reach 7.
