Research on the Active Guidance Control System in High Speed Maglev Train [PDF]

IEEE Access, 2019
The guidance system is one of the important subsystems of high-speed maglev train. The active guidance of high-speed maglev train is achieved by the attraction between the guide way and the electromagnets mounted on the side of the carriage.
