A study and experiment on the stabilization characteristic and the stiffness in Active Magnetic Bearing

자기베어링시스템 강성의 실험적 고찰을 통한 안정화 특성에 관한 연구

Due to the lack of stiffness and difficulties of control, it is hard to achieve well balanced magnetic levitation. In this paper, we analysis the current and position stiffness change according to bias current through experiment. Then, compensation equations were presented. After obtaining PD gain for each bias current and PD gain region through levitation experiment, we consider the characteristics.
