摘要：
The variable length segmented linear induction motor (VLS-LIM) parameters are featured with discontinuous, rapid time-varying, and strong coupling, which poses challenges to transient electromagnetic modeling. This paper introduces three time-varying factors and derives analytical expressions of VLS-LIM with time-varying properties. A mathematical model is established by analyzing the electromagnetic coupling characteristics between the stator and mover and the coupling relationship between the time-varying factors and state variables. Simulation results show that the mathematical model's voltage, current, and speed differ from the finite element calculation by less than 6%, verifying the accuracy of the proposed mathematical model. Hardware-in-the-loop experiments show that the mathematical model accurately characterizes the complex electromagnetic transient under high-speed working conditions, verifying the model's decoupling ability and calculation stability. ©2024 Chin.Soc.for Elec.Eng.
