摘要

At present, the suspension-type train generally uses the rubber wheel as the running wheel and the rotating motor as the driving core. In the long-term operation process, the rubber wheel will cause the train operation to be bumpy and increase the maintenance cost due to serious wear. In this paper, the linear switched reluctance motor (LSRM) is applied to the suspension-type train, and the basic control model of LSRM is built, and its effectiveness is proved under the current chopping control (CCC). Through the in-depth analysis of the direct thrust and normal force control of LSRM, a direct thrust and normal force control strategy based on cosine thrust distribution function is proposed, which can effectively improve the start-up performance and reduce the thrust drop during the phase transformation. At the same time, it can limit the normal force to be less than the vehicle weight, and still meet the needs of the suspension-type train under the condition of uneven road surface.
