A new four-dimensional chaotic system with complex phase portraits and its circuit simulations

Le résumé fourni par la source

Chaotic systems with high complexity are preferred in the fields where unpredictability and randomness of chaotic systems are required. In this paper, we propose a new four-dimensional chaotic system with complicated phase diagrams. It has only one unstable equilibrium point. Phase diagrams, Poincarémaps, symmetry properties, Lyapunov exponents, and bifurcation diagrams of the proposed system are discussed. The spectral entropy complexity of its output value is also calculated and compared with that of some existing chaotic systems. The comparison shows that the system is of relative high complexity that is welcome in many fields where high unpredictability and randomness are needed. Circuit simulations with Multisim 14 are also provided to indicate the realizability of the system.
