Modeling of the Transient Switching Process of Segmented Stator Long Primary Linear Induction Motor in Series-Fed

When the segmented long primary linear induction motor (LPLIM) is powered by segments series-fed method, the motor parameters do not vary with the rotor movement even during the mover crossing the two stator segments. However, the segments series-fed method may results in the switch layout complexities, especially during the switching process. To address this, the transient switching process of the dual three-phase linear induction motor is analyzed and a corresponding phase-domain model is developed by introducing a coupling matrix and current constraint matrix. The model and control effectiveness are validated through simulation results based on a test platform of LP-DSLIM in our Lab.
