The nonlinear dynamics time evolution of an electromagnetically levitated (EML) droplet is considered in this study. The droplet is modeled as a three dimensional system with lumped masses and elastic springs. A new expression for the spring elastic constants in a global stiffness matrix has been derived, and equations of motion presented. The chaotic behavior of the system is analyzed for different...
This paper deals with the control in both horizontal and vertical directions of a nonlinear magnetic spherical particle suspension. A pair of horizontal electromagnets were added to the typical magnetic levitation system in order to handle the horizontal unexpected displacements of the particle. A fuzzy logic controller was designed to bring the particle to the operating location situated on the symmetry...
