CONTROL OF A LINEAR SYNCHRONOUS MOTOR FOR MAGNETICALLY LEVITATED VEHICLES

The paper discusses a control system for such motors, which is a propulsion system favored for the next stage of the German electrodynamically-levitated train project. Feedback signals of vehicle position and levitation height must be available in the wayside power converters. A novel vehicle position detector is described in which these signals are calculated from electrical data measured at the stator winding terminals. An electrical model of the motor is used in conjunction with a phase-locked loop to obtain the signals of vehicle position required by the control system.
