Dynamic characteristic analysis of LIM using coupled FEM and control algorithm

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.
