1 I n t r o d u c t i o n With ever increasing demands placed on precision and reliability within manufacturing and research environments, magnetic levitation systems are finding increased utilization within such applications as machine tooling due to their non-contact (i .e. , low friction) force exertion and their capability for active at tenuation of mechanical vibrations. However, magnetic ...

This paper presents a nonlinear servo-control design based on Fuzzy model for safer and comfortable levitation of an electromagnetic suspension stage consisting of triple arrangement of hybrid electromagnets, since conventional linear control design can give satisfactory results only around a specified linearization point for tiny displacements. The authors have proposed compensation principle ...

We report an experimental highdelity system for making psychophysical measurements on human operators performing real, virtual, and real-remote 3D haptic manipulation tasks. Operators interact with task environments through six-degree-of-freedom (6-DOF) Lorentz magnetic levitation haptic devices. This arrangement allows the operator to exert and experience real, virtual, and real-remote forces/...

This work proposes a systematic two-degree freedom control scheme to improve the reference input tracking and load disturbance rejection for an unstable magnetic levitation system. The proposed control strategy is a two-step design process. Firstly, a proportional derivative controller is introduced purposely to get the desired set-point response of the magnetic levitation system and then, an i...

A longstanding goal in biomedical research has been to create organotypic cocultures that faithfully represent native tissue environments. There is presently great interest in representative culture models of the lung, which is a particularly challenging tissue to recreate in vitro. This study used magnetic levitation in conjunction with magnetic nanoparticles as a means of creating an organize...
