As a means of mass transportation, the safety and passengers’ comfort of maglev trains are paramount. Nevertheless, evaluating the two indices of maglev trains is challenging based on individual error measures. Of note, track irregularities on a maglev line may introduce unsafety concerns and discomfort for passengers. Finding a suitable control scheme that balances trade-offs is a complex issue. This paper presents a new model for chassis control to address this challenge, jointly considering secondary suspension dynamics (connecting chassis and carriage) and track irregularities. Then, we first develop an adaptive disturbance observer(ADO) and a novel safe backstepping control barrier function (CBF) to reject track irregularities and prevent physical contact (unsafety issue), and extend to address ride comfort. Moreover, the feasibility of the proposed method associated with the conflicts between safety and passenger comfort is analyzed. Finally, The trade-off between safety and ride comfort is mediated by a quadratic program (QP). A substantial amount of simulation results validate that the proposed control method addresses the ride comfort and safety of maglev trains well.
