An Optimized Electric Propulsion System for Hyperloop Applications

Abstract

In this paper, an advanced electric propulsion system (EPS) is designed for an ultra-fast electric train. The proposed system consists of a slotless dual-sided linear synchronous motor (DSLSM) and a three-step track powering topology. A multi-objective 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 airgap 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.
