Identification of Active Magnetic Bearing Actuator Using Unbalance Compensation Method
불균형 보상법을 이용한 능동 자기베어링 구동기의 동특성 규명
Abstract
In this study, the in-situ parameter identification method for active magnetic bearing (AMB) actuator based on an open-loop balancing scheme is proposed. The scheme utilizes the relation between the compensating voltage and the known unbalance force. Main advantage of this method is that it is easy to use, yet it gives the actuator dynamics on the actual operating condition of an AMB system. The experimental results show that the proposed scheme compensates the known unbalance accurately and consequently identifies the actuator dynamics effectively.
