Model Establishment and Simulation Analysis of Permanent Maglev Vehicle

Based on the principle of variable magnetic flux, a permanent magnet suspension vehicle is proposed in this paper. The device adopts a four-point suspension structure and provides driving force through a permanent magnet gear. By changing the rotation angle of the disk permanent magnet of the four magnetic poles, the magnetic flux is changed. It could achieve the suspension force equal to gravity, so that the stable suspension of the device is realized. According to the suspension force model and the structure of prototype, a control decoupling system model is established. The decoupling strategy changes the four-point independent control into the control suspension vehicle with three degrees of freedom. The simulation results show that the decoupling control method is effective and worthy of further verification through experiments.
