Abstract

The invention discloses a maglev train, a levitation control system and a method for improving operation stability, and relates to the field of levitation control. In order to avoid the influence of track irregularity interference on the levitation control stability of the maglev train, after an irregularity interference estimated value is obtained, feed-forward control is used for applying dynamic compensation to the track irregularity, so that the adverse influence of the irregularity interference on the levitation control stability can be greatly weakened, the maintenance period of the track is prolonged, the operation cost is reduced, and the operation stability and comfort of the maglev train are further improved. By adding feedforward control, the anti-interference capability of the levitation control system of the maglev train is improved, the robustness and environmental adaptability of the levitation control system are improved, and the used feedforward control and feedback control policy can also be migrated and used for other similar scenes.

Description

technical field [0001] The invention relates to the field of suspension control, in particular to a maglev train, a suspension control system and a method for improving running stability. Background technique [0002] The maglev transportation system is a complex electromechanical system integrating mechanical engineering, control engineering, civil engineering and other disciplines. There is a strong interaction between each system, and the dynamic behavior of train operation is very complex. The maglev train relies on the electromagnetic force generated by the active control electromagnet to levitate and guide, and runs around the slender track beam under the propulsion of the linear motor, avoiding the direct mechanical contact between the vehicle and the track, but a lot of dynamic problems still exist. The nonlinear active magnetic buoyancy of the maglev system makes the research on the dynamics of the maglev vehicle system very special. The stability of the control sys...
