Smooth section crossing of controlled-repulsive PM LSM vehicle by DTC method based on new concept of fictitious section

This paper presents propulsion control for the permanent-magnet linear synchronous motor vehicle Marine-Express 03 (ME03) to pass through the two sections in the mass-reduced mode by a new direct torque control (DTC) method. A fictitious section is introduced for pass-through-section control. It has been done by introducing a fictitious section defined by "one section including section boundary." The lift and thrust forces for the pass-through section are obtained by the DTC method based on voltage equations per one fictitious section. The vehicle ME03 has been controlled successfully to pass through the two sections in the mass-reduced mode by experiment.
