Disclosed are a method and system for correcting the precision of a magnetic levitation train traction system position control ring. The precision correction method comprises: step A, a speed measuring system collecting position-related information of a train; step B, sending the position-related information to a traction system through a signal system; and step C, the traction system carrying out closed-loop control on the position of the train according to the position-related information. The method further comprises step A1 before step A: checking the time for the speed measuring system, the signal system and the traction system, and adding timestamp information. According to the correcting method and system, the time is checked for a speed measuring system, a signal system and a traction system, and timestamp information is added, such that the influences of a delay and periodic random shaking are overcome, and the requirement of traction control of a medium-high speed magnetic levitation train is met. By using mature and cheap 4G-LTE wireless communication, the characteristics of high bandwidth, low delay, wide coverage, QoS guarantee and high-speed movement are achieved. A simple and practical method for improving precision of medium-high speed magnetic levitation magnetic pole phase angles is provided, and this has good engineering application prospects.
