A new modified hyperchaotic Lü system

This paper proposes a new four-dimensional continuous autonomous hyperchaotic system, which is constructed based on a modified Lü system by introducing a nonlinear state feedback controller. The detailed dynamical behaviors of this hyperchaotic system are further investigated, including equlibria and stability, various attractors, bifurcation analysis, and Lyapunov exponents spectrum. Moreover, a novel analog circuit diagram is then designed for verification of various attractors.
