The suspension module control system model has been established based on MIMO (multiple input and multiple output) state feedback linearization. We have completed decoupling between double suspension points, and the new decoupling method has been applied to CMS04 magnetic suspension vehicle in national mid-low-speed maglev experiment field of Tangshan city in China. Double suspension system mod...

Abstract: In order to realize the high speed and high-precision control of a maglev planar motor, a high-precision electromagnetic model is needed in the first place, which can also contribute to meeting the real-time running requirements. Traditionally, the electromagnetic model is based on analytical calculations. However, this neglects the model simplification and the manufacturing errors, w...

This study presents the design of a magnetically levitated (maglev) axial magnetic flux brushless direct current motor (AF-BLDC) for an axial blood flow ventricular assist device (VAD). It has three phases, twelve salient stator poles, and eight rotor magnet poles. It is designed in miniature size. Twin AF-BLDC motors are placed in the VAD symmetrically and rotors are coupled to the pump from t...

Abstract As an important bearing structure of maglev train, the connecting rod has high requirements for material performance. In this paper, according to structural capacity rod, finite element methodwas used calculate and analyze composite aluminum alloy under two working conditions, so as determine advantages in mechanical properties provide theoretical support design rod.

magnetic levitation (maglev) is amongst the most advanced technologies that are available to the transportation industries. it has already been noticed by decision makers in many countries around the globe. contrary to such high levels of interest, there are no practical algorithms available to the engineers and/or managers to assist them in analyzing economics of the maglev systems. therefore,...

An electromagnetic levitation controller design considering guideway deflection is presented. Even though to design a maglev controller to make a vehicle steady suspension under guideway deflection is a key technology in maglev vehicle system, the vehicle-guideway interaction effects haven’t well explored and yet settled. Unlike most approaches based on the linear model, a maglev controller is ...

SWISSMETRO is a MAGLEV Project, designed for a speed up to 500 km/h in two tunnels under partial vacuum. The authors investigate new possibilities to combine the propulsion and levitation. Polarized inductors for the levitation are studied, implying a polarized (permanent magnet) synchronous linear motor. The thermal behavior is investigated using a numerical platform of the complete vehicle-tu...
