SENSORLESS MAGNETIC DAMPING GENERATING METHOD EMPLOYING INDUCTION CURRENT-COLLECTOR

摘要

PROBLEM TO BE SOLVED: To provide a sensorless magnetic damping generating method employing an induction current-collector in which a sensor for measuring vibration of a vehicle is not required and a closed system can be configured only with an induction current-collector. SOLUTION: In the magnetic damping generation method employing an induction current-collector, induction voltage variation proportional to displacement of a vehicle is estimated by an observer and magnetic damping proportional to vibration speed is generated from its estimation information.
