Bifurcations and Hyperchaos in Magnetoconvection of Non-Newtonian Fluids

Abstract: We report the existence of multiple bifurcations, period-doubling route to chaos and hyperchaos in magnetoconvection of a shallow, electrically conducting non-Newtonian couple-stress fluid layer heated from underneath with vertically imposed magnetic field. By adopting low-order approximations, a four-dimensional dissipative hyperchaotic system with six control parameters is obtained. Both fluid couple-stress and magnetic parameters delay the onset of convection. In contrast to plain couple-stress convection, … Show more

“…In this paper, we propose a observer based synchronization under a master-slave configuration. Such scheme, lie in a fuzzy-based sliding-mode observer (FSMO) design for a hyperchaotic Lorenz-type system reported in Reference [24]. Firstly, the proposed methodology consists in designing a SMO for the hyperchaotic system by means of Lyapunov analysis.…”
