Design of the position estimator for propulsion inverter driving long stator LSM

This paper presents the position estimator for propulsion inverter driving long stator linear synchronous motor in high speed maglev train. In order to get the higher resolution of the position information transmitted from vehicle, Full order state observer is used for position estimator. Theoretical basis, simulation results show the proposed strategy can meet the dynamic property need of propulsion control system with long state linear synchronous motor.
