A study on the slip frequency control of linear induction motor for magnetic levitation transit

자기 부상 열차용 리니어모터의 슬립 주파수 제어에 관한 연구

In this study, a variety of characteristics is considered when LIM for transit is driven with acceleration and deceleration. From the characteristics of constant voltage, with V/f ratio fixed, slip frequency is derived. With slip frequency of 12[Hz] and objective velocity of 40[km/h], the robust control characteristics which are generated constant thrust and normal force, except for open-loop control interval, are obtained.
