摘　　要：高速磁浮交通系统采用长定子直线同步电机驱动技术,直接影响系统的最高速度、加减速能力和运行效率,也与悬浮系统和导向系统强耦合,进而会影响系统的安全性、经济性和舒适性。文章分析了国内外高速磁浮交通系统驱动技术,论述了高速磁浮长定子直线同步电机的现状与不足,在对存在问题和挑战进行讨论的基础上,围绕优化长定子直线同步电机结构、精确计算长定子直线同步电机复杂变工况高速运行动态性能和复杂应用环境适应性设计3个问题,提出了针对600 km/h速度级高速磁浮交通系统驱动技术研究与开发的建议。The high-speed maglev train adopts driving technology of long-stator linear synchronous motor,which directly influences the maximum operating speed,acceleration and deceleration capability and operating efficiency of system.It is also strongly coupled with levitation system and guidance system,and then affects the safety,economy and comfort of system.This paper analyzes the driving technology of high-speed maglev transportation system at home and abroad,and then discusses the status and shortage of long-stator linear synchronous motor for existing high-speed maglev train.Based on viewing existing problem and challenges,the research and development directions of driving technology for 600 km/h high-speed maglev transportation system are proposed according to three aspects including the structure optimization of long-stator linear synchronous motor,precise calculation of long-stator linear synchronous motor running dynamic performance under complicate variable working condition,and adaptability design of complex application environment.
