Investigation of SLIM Dynamic Models Based on Vector Control for Railway Applications

Although, Single-Sided Linear Induction Motor (SLIM) utilization has increased in railway applications due to theirnumerous advantages in comparison to Rotational Induction Motors (RIM), there are some sophistication in theirmathematical models and electrical drive. This paper focuses on the problems of SLIM modeling, with assumingend-effect on the basis of Field Oriented Control (FOC) as a drive control method. To do so, two dynamic modelsof SLIM are described and investigated. To evaluate their technical characteristics (i.e., thrust, torque, current, andspeed) and also motor performance, a comparison is realized for synchronous and stationary reference frames in bothdynamic models. Further, the disparities of these two dynamic models and FOC operation in the two reference framesare discussed. Finally, the validity of the control method accuracy is verified for each model by simulation results.
