Analysis and Design for hybrid Magnetic Levitation Controller in Medium-Low Speed Maglev Train

The medium-low speed maglev train makes full use of electromagnetic force to achieve active levitation and drives the train by the linear motor. In order to increase the carrying capacity of maglev train significantly and improve the levitation energy consumption, a new hybrid levitation system comprised of permanent magnet and electromagnet is proposed and applied to the medium-low speed maglev train. In this paper, the mathematical model of hybrid levitation system is established, and the controller is designed to have the ability to levitate the maglev train stably.
