A Fractional LQI Controller for a Magnetic Levitation System
2021 25th International Conference on Methods and Models in Automation and Robotics (MMAR), 2021A magnetic levitation plant is a fast, unstable, nonlinear mechatronic system vulnerable to measurement noise and external interference. Designing a high-performance and robust controller for such system, immune to noise and disturbances, and ensuring a wide operating region, is a challenging task.

Modeling of magnetic levitation system
2017 21st International Conference on Process Control (PC), 2017The paper is devoted to modeling and parameter identification for Magnetic Levitation System (MLS) from Inteco. MLS belongs to challenging modelling and control problems due to its unstability and nonlinearity. We concern several modeling details not sufficiently described in user manual, a correction of nonlinear model, and present the corresponding ...

Levitation and Propulsion Control of a Magnetic Levitation System with Two Degrees of Freedom
Proceedings of the 44th IEEE Conference on Decision and Control, 2006The design and implementation of a control scheme for the levitation height and angular position reference tracking in a two degrees of freedom levitation system is presented. The levitation system prototype is described and a nonlinear model that reflects its dynamic behaviour is obtained.

A new magnetic levitation system with AC magnets
IEEE Transactions on Magnetics, 1988A magnetic levitation system using AC magnets is proposed that has iron rails with primary windings on the ground and levitation magnets with secondary windings placed on the levitated object. A constant AC current is supplied to the primary windings and currents are induced in the secondary windings by magnetic coupling between the primary and ...

Superconducting bulk magnets for magnetic levitation systems
Physica C: Superconductivity, 2000Abstract The major applications of high-temperature superconductors have mostly been confined to products in the form of wires and thin films. However, recent developments show that rare-earth REBa2Cu3O7−x and light rare-earth LREBa2Cu3O7−x superconductors prepared by melt processes have a high critical-current density at 77 K and high magnetic ...

Magnetic Levitation Systems and Microelectromechanical Systems
2020We derive the mathematical model of both systems. In particular, the magnetic levitation system that we consider is that of a levitated ball whereas an electrostatic micromirror is the microelectromechanical system that we consider. We formally solve the position regulation problem in both systems.

Networked predictive control of magnetic levitation system
2009 IEEE International Conference on Systems, Man and Cybernetics, 2009This paper discusses the control of a magnetic levitation (MagLev) system over networks. In order to improve the control performance, the networked predictive control method is employed based on the feedback linearization and direct local linearization models of the nonlinear MagLev system.

Force Calculation for Hybrid Magnetic Levitation System
2018 14th International Conference on Computational Intelligence and Security (CIS), 2018This paper presents a calculation model for the electromagnetic force of the hybrid magnetic levitation systems composed of electromagnets and permanent magnets, based on which, theoretical derivation is presented for electromagnetic induction intensity distribution of a single solenoid. According to the molecular circulation hypothesis and Biot-Savart

Nonlinear Robust Control of a Magnetic Levitation System
First International Conference on Innovative Computing, Information and Control - Volume I (ICICIC'06), 2006This paper deals with the design of a nonlinear robust control scheme for a magnetic levitation system. We define a new switching function to form a variable structure feedback control in order to help improve tracking performance of the system. We practically implemented the controller in an experimental magnetic levitation system and investigated its

Reviewing Propulsion & Levitation System for Magnetic Levitation Train
2021 9th International Electrical Engineering Congress (iEECON), 2021In this paper, we aim to review and design propulsion, levitation system for magnetic levitation train (Maglev). Since the maglev train use high technologies to design that may become a normally transportation in future. And because in Thailand, there rarely have about maglev study project.
