摘要
高速磁浮直线同步电机推力波动是制约高速磁浮列车安全性的瓶颈之一,推力波动的抑制是提升磁浮列车安全可靠性与平稳舒适性的关键技术。本文对比常导高速磁浮与超导高速磁浮技术,介绍推力波动抑制的关键问题,概述悬浮间隙波动抑制控制方法、长定子直线同步电机精确建模以及推力波动抑制方向.
The thrust fluctuation of the high-speed maglev linear synchronous motor is one of the bottlenecks restricting the safety of the high-speed maglev train.The suppression of thrust fluctuation is the key technology to improve the safety,reliability,stability and comfort of the maglev train.This paper compares the technology of high-speed maglev with that of superconducting high speed maglev,intoduces the key problems of thrust fluctua-tion suppression,summarizes the research progress and shortcomings of suspension gap fuctuation suppression method,accurate modeling of long stator linear synchronous motor,and thrust fluctuation suppression control method,and proposes the future research direction in thrust fluctuation suppression of high-speed maglev linear synchronous motor.
