능동자기베어링 시스템에서 PD와 PID 제어기의 특성 비교
Abstract
Basic governing equations for the Active Magnetic Bearing system are derived. Characteristic difference between PD and PID controllers are studied. It is shown that I-control action is able to minimize the steady state error and increase the stiffness in low frequency range.
