Levitation Control Experiment at Standstill in PM LSM Controlled-Repulsive Maglev Vehicle
Kinjiro YOSHIDA,Hiroshi TAKAMI,Chiyuki JOZAKI,Shizuo KINOSHITA 전력전자학회 1998 ICPE(ISPE)논문집 Vol.- No.-
This paper proposes a new repulsive-Maglev vehicle in which a vertical type PM linear synchronous motor (LSM) can levitate and propel simultaneously, independently of the vehicle speeds. A compact control method is developed which is based on the concept of controlling individually the levitation system by armature-current and the propulsion system by mechanical load-angle. The levitation-motion control experiments have carried out successfully together with positioning at standstill. The pitching motion has been compensated for very well by using the zero-phase-current control method proposed here.<br/>
Intelligent-CCS Fed Marine-Express Model Train Me03 in Mass-Reduced-Mode
Kinjiro Yoshida,Hiroshi Takami,Hazime Mihara 전력전자학회 1998 ICPE(ISPE)논문집 Vol.- No.-
This paper presents a new high-performance intelligent controlled current-source (CCS) system which can compensate for modelling errors of armature resistance, leakage and magnetizing inductances and for space harmonic components of speed EMF's. A shuttle-motion simulation is presented in the mass-reduced-mode in which an equivalent vehicle weight is reduced, by 40kg, from 47kg to 7kg.<br/> This study provides one of the most important key-technologies in driving practical linear synchronous motor (LSM) Maglev vehicle.<br/>
