N2 - P328-magnet linear synchronous motor (PMLSM) has been widely used in the long-distance linear transportation system. The PMLSM with the discontinuous arrangement of the stators has been proposed to reduce the cost and increase the flexibility. However, the transportation system leads to control challenges that the sensors cannot be installed in the whole stator, the unfixed electromagnetic parameters, and the deceleration when the mover is moving out of the stator. In order to overcome these problems, the sensorless control of the PMLSM using the pre-calibrated parameters is proposed in this paper. The control is divided into three processes: Entering Process, Coinciding Process and Leaving Process. The electromagnetic parameters between the mover and the stator can be calibrated in Entering Process. Then, with accurate calibrated parameters, the sensorless control based on the improved back-EMF integration method is proposed in Coinciding Process. In Leaving Process, the speed of mover can be maintained using the position information from the grating head to overcome the electromagnetic drag force. The theoretical derivation and simulations show the effectiveness of the sensorless control using the pre-calibrated parameters.
