Dynamic Characteristic Analysis of LIM Using Coupled FEM and Control Algorithm

유한요소법(FEM)과 제어알고리즘이 결합된 기법을 이용한 선형 유도전동기(LIM)의 동특성 해석

It is necessary to modify the state-of-the-art of vector control theory, because of the phase asymmetry(static end effect) in the Linear Induction Motor(LIM). The dynamic characteristic analysis method of the vector controlled LIM using coupled FEM and control algorithm taking into account the movement is proposed. The focus of this paper is the analysis relative to phenomena of static end effect due to the motor structure. To prove the propriety of the proposed method, the Digital Signal Processor(DSP) installed experimental devices are equipped and the experiment is performed.
