Abstract
For long-stator linear synchronous motors (LSLSM) applied in electromagnetic suspension (EMS) maglev trains, sensorless control schemes are generally considered, especially when the train is running at a high speed. However, as a result of the coupling between the traction control system and the levitation control system on a maglev train, the disturbance occurred in the levitation system will also cause instability of sensorless control applied in the traction system. In this paper, the filtering method is adopted to reduce the disturbances of the levitation system and ensure the stability of the sensorless control scheme in the traction system.
