Study on controllable suspension force of AC coupled maglev

Aiming at the problem of high AC control difficulty, an AC coupled vector controllable suspension force scheme is proposed, the two-phase coupling is solved, analyzed and calculated, and the T-type decoupling equivalent is carried out, and the physical resonance complete decoupling method is proposed. The calculation and simulation results show that the AC maglev can meet the amplitude and phase conditions at the same time, and the DC equivalent controllable suspension force can be generated and realized. The DC control method can be used to reduce the difficulty of AC control, which provides a new structure reference for AC maglev.
