Abstract :
This paper presents a new high-performance observer system based on the extended Kalman filter (EKF) which can compensate for space-harmonic components of speed EMF in sensing the position and speed of a Marine-Express model train ME03. The simulation for shuttle motion is presented in the mass-reduced-mode in which the vehicle weight is reduced from 47 kg to 7 kg. This study provides one of the most important key-technologies in practical LSM Maglev systems
