Application of Sensorless Control Technology of Permanent Magnet Synchronous Motor in Tianjin Metro
The necessity of sensorless control technology of permanent magnet traction system in the field of rail transit was introduced, the position estimation method based on the electromagnetic relation of permanent magnet motor was summarized, and the performance indexes of position sensor and sensorless control technology were compared, which proved that sensorless control technology could completely replace position sensor. Ground test and loading test showed that the sensorless control technology could fully meet the requirements of subway operation under various working conditions.
