KGaA, Weinheim (1 of 10) 1600144 wileyonlinelibrary.com based on their refractive index and size.[4] Label-free approaches eliminate the need for cell markers and allow separation based on intrinsic cell properties. Magnetic levitation enables label-free, sensitive, and specific density measurements of particles which are suspended in a paramagnetic medium and...

The recent advances in levitation methods for materials processing now enable structural, thermo-physical property, and phase transition studies to be made on high temperature solids and liquids without container contamination. These studies have led to new insights into the liquid state and have revealed how local order in the liquid can dictate phase formation. In this article, levitation tec...

This paper addresses real-time magnetic levitation control with analog and digital controllers. The objective is to keep a ferromagnetic object suspended, without contact, beneath an electromagnet. The electromagnetic force must be adjusted to counteract the weight of the object and account for disturbances. This is accomplished by measuring the location of the object using a non-contact sensor...

SWISSMETRO is a MAGLEV Project, designed for a speed up to 500 km/h in two tunnels under partial vacuum. The authors investigate new possibilities to combine the propulsion and levitation. Polarized inductors for the levitation are studied, implying a polarized (permanent magnet) synchronous linear motor. The thermal behavior is investigated using a numerical platform of the complete vehicle-tu...

The present report summarizes the work conducted during the internship on Feedforward Control of the Magnetic Levitation Setup. Different feedforward strategies, specifically tailored for this setup, are developed and reviewed. These feedforward methods explicitly take the intrinsic position-dependent behavior of the magnetic levitation setup into account. Additionally, closed-loop stability of...
