| Abstract: | In the high-speed maglev system, accurate real-time information of the train position is essential for stable, safe and efficient train operation. To detect the relative position of the high-speed maglev train from a reference position, a location method based on long stator slot detection was proposed. Besides, a prototype system has been successfully developed. The hardware structure of the system, as well as its working principle was described. Moreover, a subdivision algorithm for calculating the pole location angle signal was elucidated. Experiments show that the proposed method is feasible. The technical indexes of the detection system satisfy the requirements of the vehicle operation control system. The relative position sensing system can be put into practice. |
