摘　　要：常导高速磁浮列车悬浮导向控制系统通过主动调整电磁力以实现车辆与轨道之间的无接触运行,是保障列车高速平稳运行的核心关键系统。文章从悬浮导向系统非线性稳定控制、耦合振动抑制控制、抗扰控制、故障诊断与容错控制4方面介绍了悬浮导向控制关键技术与发展现状,围绕悬浮导向系统的失稳机理、悬浮导向系统与列车及轨道的关键参数匹配、悬浮导向系统性能智能恢复控制、悬浮导向系统状态智能评估等方向总结了高速磁浮列车工程化应用将面临的技术挑战和未来展望。最后,对如何提升高速磁浮列车运行稳定性、平稳性和可靠性提出了发展建议。The levitation and guidance control system of the EMS high-speed maglev train realizes the contactless operation between the vehicle and the track by actively adjusting the electromagnetic force,which is the core system to guarantee the high-speed and smooth operation of the train.This article introduces the key technology and development status of levitation and guidance control from four aspects,including levitation and guidance system nonlinear stability control,coupled vibration suppression,disturbance attenuation,fault diagnosis and fault-tolerant control.And it summarizes the technical challenges and future prospects of the engineering application of high-speed maglev trains,including the mechanism of levitation and guidance instability,the matching of key parameters of the levitation and guidance system with the train and the track,the intelligent recovery control of levitation and guidance performance,and the intelligent assessment of the state of the levitation and guidance system.Finally,it proposes development suggestions on how to improve the stability,smoothness and reliability of high-speed maglev train operation.
