Model predictive controllers for magnetic levitation systems
2015 IEEE 10th Jubilee International Symposium on Applied Computational Intelligence and Informatics, 2015The paper presents the design and the implementation of two model predictive controllers (MPCs) for magnetic levitation systems. The presentation is focused on the position control of a sphere in a magnetic levitation system with two electromagnets laboratory equipment in order to test the proposed controllers.

Control Education on Magnetic Levitation System
2021 23rd International Conference on Process Control (PC), 2021This paper presents education potential of our recently published results which are further extended and applied on Magnetic levitation system (MLS) modeling and control. We focus on linearized state-space control design approaches and propose robust pole-placement controller in the presence of model uncertainties.

Variable structure control of a magnetic levitation system
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001Presents a variable structure control (VSC) design procedure for robust stabilization and disturbance rejection of a magnetic levitation system. The procedure is based on a method called the reaching law method complemented by a sliding mode equivalence technique.

IEEE Transactions on Applied Superconductivity, 2007
In the conventional conveyance system, noise, friction and vibration occur under operation. We have developed the hybrid magnetically levitated system. In this system, pinning force of high temperature bulk super conductor is used for the levitation and guidance. This system needs no control system for levitation and guidance.

Nonlinear disturbance rejection for magnetic levitation systems
Proceedings of the 2003 IEEE International Symposium on Intelligent Control ISIC-03, 2003In this paper, a position regulation control strategy is developed for a magnetic levitation system operating in the presence of a bounded, nonlinear, periodic disturbance. The proposed controller utilizes a saturated control force input in conjunction with a learning based disturbance estimator to asymptotically regulate the target mass to a desired ...

Magnetic Levitation System by Reluctance Control: Levitation by Motion Control of Permanent Magnet
International Journal of Applied Electromagnetics and Mechanics, 1994A new type of active magnetic levitation system is proposed. In this system, the forces of permanent magnets are used for levitation and controlled by adjusting the reluctance of the magnetic circuit. Using permanent magnets, the feature of this system is effective for saving energy and avoiding heat generation.

Effects of magnetic history on the levitation characteristics in a superconducting levitation system
Physica C: Superconductivity and its Applications, 2008Using an updated high-temperature superconductor maglev measurement system, influences of the motion mode in which both the superconductor and the magnet are placed close to each other on the magnetic forces and their relaxation are measured. It is found that Method 1, in which the magnet coaxially approaches the superconductor which is subsequently ...
