摘要
En 中文
In this article, an advanced electric propulsion system (EPS) is designed for an ultrafast electric train. The proposed system consists of a slotless dual-sided linear synchronous motor (DSLSM) and a three-step track powering topology. A multiobjective optimization workflow based on a reduced-order model of DSLSM is used to optimize the permanent magnets (PMs) and the winding dimensions to maximize the thrust force density and efficiency. The optimized model is validated using the finite-element analysis (FEA). Then, a new fault-tolerant control algorithm is proposed for the optimized DSLSM fixing the mover in the center of the DSLSM under any air-gap disturbance. Finally, a high-fidelity switching model of the complete EPS is developed. The performance of the proposed EPS is verified using a real-time hardware-in-the-loop (HIL) simulator under normal and faulty conditions.
