Abstract

The invention discloses a control method of suspension force of a normal conducting magnetic-levitation train. The method comprises following steps: obtaining travelling speed, travelling direction, suspension gap and acceleration information of a normal conducting magnetic-levitation train; obtaining decrement [delta] F of corresponding suspension force according to the travelling speed and the travelling direction; obtaining increment [delta] i of corresponding current according to the decrement [delta] F of suspension force; obtaining corresponding given current i* according to the suspension gap and the acceleration; superposing the given current i* and the current increment [delta] i to obtain rectified given current I; operating the rectified given current I to obtain corresponding real control current i; outputting the real control current i to the coil of the suspension electromagnet. The above method can compensate the influence of track eddy current on control performance of a suspension system of a normal conducting magnetic-levitation train. In addition, the invention also discloses a control system of suspension force of a normal conducting magnetic-levitation train and a suspension controller.

Description

technical field [0001] The invention relates to the technical field of levitation control of maglev trains, in particular to a levitation controller, a levitation force control method and a system for a constant conduction maglev train. Background technique [0002] During the operation of the conventional maglev train, the levitation electromagnet and the track move relative to each other, and eddy currents will be generated inside the track. Since the track generally adopts an integral rolling structure instead of a laminated structure, the eddy current effect is relatively large, and the magnetic field generated will be weakened. The air gap magnetic field between the suspension electromagnet and the track leads to the reduction of the suspension force, which affects the control performance of the suspension system. The current traditional method is to add a permanent magnet at the end of the levitation electromagnet to compensate for the influence of the orbital eddy cur...
