This paper reviews and summarizes Maglev train technologies from an electrical engineering point of view and assimilates the results of works over the past three decades carried out all over the world. Many researches and developments concerning the Maglev train have been accomplished; however, they are not always easy to understand. The purpose of this paper is to make the Maglev train technologies clear at a glance. Included are general understandings, technologies, and worldwide practical projects. Further research needs are also addressed.read more

Sliding mode and classical controllers in magnetic levitation systems
TL;DR: In this paper, an experimental comparison between a sliding-mode controller and a classical controller for stabilizing and commanding a magnetic levitation system is made, where the sliding mode method can be applied to a nonlinear system in the global sense, and the issues of performance and robustness to modeling uncertainties and disturbances can be directly incorporated in the design as tradeoff parameters.

A new MAGLEV system for magnetically levitated carrier system
TL;DR: In this article, a power-saving electromagnetic suspension system was developed in which electromagnets with permanent magnets were used to suspend the vehicle and the electromagnetic coil current required to keep a vehicle levitating was extremely small, ideally zero.

The Inductrack: a simpler approach to magnetic levitation
Richard F. Post,D. D. Ryutov +1 more
TL;DR: The Inductrack as mentioned in this paper is a model-scale magnetic levitation system, which employs special arrays of permanent magnets on the moving car to induce repelling currents in a close-packed array of shorted circuits in the track.

Decoupling control of thrust and attractive force of a LIM using a space vector control inverter
Isao Takahashi,Y. Ide +1 more
TL;DR: In this paper, a new control method for magnetic levitation vehicles using linear induction motors is described, which can generate both thrust and attractive force. But it is not suitable for relatively low-speed vehicles, such as an urban transit system.
