摘要
Abstract
The electromagnetic damping of the superconducting electrodynamic maglev train is low during the operation.With the assistance of the propulsion control of the linear synchronous motor,a levitation stability control system is designed for a technical guarantee for the levitation stability of the train.Taking the superconducting electrodynamic maglev train of the MLX01 as the research object,combined with the field-circuit-motion coupling numerical model composed of a single bogie and ground coils,the levitation characteristics of the superconducting electrodynamic maglev train were revealed.The relationship between superconducting magnetic field strength,levitation displacement,running speed and standard air gap were studied.Analysis was made of the variation law of the electromagnetic spring coefficient in the levitation direction of a single bogie under different superconducting magnetic field strength and standard air gaps.The vector control strategy was adapted to analyze the linear synchronous motor of the superconducting electrodynamic maglev train to realize the decoupling of the components of the direct axis and the quadrature axis,and the numerical expression between the direct axis current and the levitation force was also established.A levitation stability control system was designed,and state feedback is used to realize the pole configuration of the levitation system.The balance displacement response of bogie applied before and after the levitation stability control system were compared,which proved the effectiveness of the levitation control structure.The research results show that the levitation stability control system can effectively resist external disturbances,maintain the levitation stability of the train,and further improve the ride comfort of the train.关键词
