1. Introduction From the principal point of view, the magnetic levitation is a method which is used for suspending an object in the air, without any physical contact. There are few main types of the magnetic levitation – electromagnetic, electrodynamic, transformation, superconductive and diamagnetic. All these are usually based on the force interaction between magnetic field and gravitation fi...

This paper addresses real-time adaptive Phase-lead controller for maglev systems using digital signal processors (DSP). With an adaptive phase-lead controller, the DSP automatically updates the controller parameters to achieve the desired system output. The controller is applied to maglev systems. Different adaptation rates were tested. Test results show that controller parameters converged to ...

This paper describes a method for determining the density of contact trace objects with magnetic levitation (MagLev). MagLev measurements accurately determine the density (± 0.0002 g/cm(3) ) of a diamagnetic object and are compatible with objects that are nonuniform in shape and size. The MagLev device (composed of two permanent magnets with like poles facing) and the method described provide a...
