Focusing on the traction system of high-speed maglev trains,this study adopted a hardware-in-the-loop(HIL)approach to establish a dedicated HIL simulation test platform.By combining simulation with field testing,investigations were carried out on key technologies,which include the modeling of three-level traction converters,long-stator linear motors,and vehicles,as well as the development of operation control strategies and traction control mechanisms under both single-end and dual-end power supply modes.Additionally,full-speed operation conditions were simulated.A low-speed traction experiment was conducted on a maglev test line to validate the effectiveness of closed-loop control strategies for speed and position under both single-end and dual-end power supply modes.The experimental results confirm the stable performance of the traction system and controller,the high real-time capability and accuracy of the simulation models,thereby effectively validating the feasibility and engineering applicability of the proposed approach.This provides theoretical and technical support for the design,optimization,and verification of high-speed maglev systems.
