Investigation of SLIM Dynamic Models Based on Vector Control for Railway Applications
Author(s):
Abstract:
Although, Single-Sided Linear Induction Motor (SLIM) utilization has increased in railway applications due to their numerous advantages in comparison to Rotational Induction Motors (RIM), there are some sophistication in their mathematical models and electrical drive. This paper focuses on the problems of SLIM modeling, with assuming end-effect on the basis of Field Oriented Control (FOC) as a drive control method. To do so, two dynamic models of SLIM are described and investigated. To evaluate their technical characteristics (i.e., thrust, torque, current, and speed) and also motor performance, a comparison is realized for synchronous and stationary reference frames in both dynamic models. Further, the disparities of these two dynamic models and FOC operation in the two reference frames are discussed. Finally, the validity of the control method accuracy is verified for each model by simulation results.
