Existence of Metastable, Hyperchaos, Line of Equilibria and Self-Excited Attractors in a New Hyperjerk Oscillator
In the past few years, chaotic systems with megastability have gained more attention in research. However, megastability behavior is mostly seen in chaotic systems. In this paper, a new 4D autonomous hyperjerk hyperchaotic system with megastability is reported.The new system has two modes of operation. The first mode considers one of its parameters [Formula: see text] and the second mode is [Formula: see text]. In the first mode, i.e. [Formula: see text] the proposed system exhibits self-excited attractors. But, in the second mode, i.e. [Formula: see text] the system has a line of equilibria. The new system has various dynamical behaviors. The chaotic nature of the proposed system is validated by circuit simulation using NI Multisim simulation software.
