A method, equipment and medium for levitation control of conventional maglev trains

ActiveCN122078198Aavoid security impactmaintain certaintyElectric propulsionScale modelLevitation
This invention discloses a levitation control method, equipment, and medium for conventional maglev trains, belonging to the field of maglev transportation control technology. The method constructs a control framework based on a dynamic model of the levitation system and introduces an online residual estimation and compensation mechanism to compensate for track irregularities, aerodynamic disturbances, and unmodeled dynamics under complex operating conditions. A lightweight data-driven model obtained through cloud-based large-scale model knowledge distillation is deployed in the onboard edge computing unit to model the temporal characteristics of system state, track features, and external environmental information, estimating disturbance residuals in real time and generating compensating control quantities that are superimposed on the control input. Simultaneously, the cloud continuously optimizes model parameters based on historical operating data and issues updates, achieving iterative optimization of the control strategy. This invention can significantly improve the stability, dynamic response performance, and operational safety of the maglev train levitation system under high-speed operating conditions.
