The invention relates to a maglev train suspension control method and device and a storage medium. The method comprises the following steps: acquiring a basic irregularity form of a target track beam, constructing a track irregularity model, and calculating disturbance generated by track irregularity by using the track irregularity model; constructing a nominal model of the maglev train suspension system; superposing disturbance and the nominal model of the maglev train suspension system to obtain an actual model of the maglev train suspension system; obtaining a current suspension air gap actual value, and calculating a suspension air gap error; and judging whether the suspension air gap error is 0 or not, if so, keeping the current output current size and obtaining a new suspension air gap actual value, and otherwise, outputting the optimal current size and adjusting the air gap by using a tube model predictive control-based method, and obtaining a new suspension air gap actual value. Compared with the prior art, the method has the advantages that the influence of track irregularity on the maglev train suspension system adopting the model prediction controller is fully considered, and then the robustness of the suspension system is enhanced.
