The invention relates to a position-sensorless compensation speed curve tracking system for a maglev train. The system comprises a train speed tracking controller, a speed measurement positioning subsystem, a position-sensorless speed measurement subsystem and a speed and position feedback selection module, the position-sensorless speed measurement subsystem is used for calculating the magnetic pole phase angular speed and the running speed of the train; the speed and position feedback selection module is used for simultaneously receiving speed and position information fed back by the speed measurement positioning subsystem and the speed measurement subsystem without the position sensor, and when the speed measurement positioning subsystem breaks down, the speed and position information fed back by the speed measurement subsystem without the position sensor is selected and sent to the train speed tracking controller; the train speed tracking controller is used for achieving error control and adjusting train acceleration output. Compared with the prior art, the method has the advantages that when the speed measuring and positioning subsystem breaks down, the position-sensorless speed measuring and positioning safety backup is adopted, and the train accurately tracks the preset speed curve.
