考虑轨道周期性不平顺的磁浮列车悬浮控制系统设计

以八达岭旅游线用中低速磁浮列车为研究对象,在建立悬浮控制系统模型的基础上,通过分析磁浮列车悬浮控制系统与轨道的相互作用规律,探讨了轨道周期性不平顺条件下悬浮控制系统的设计问题,比较了相对位移(间隙)、绝对速度和绝对加速度反馈与相对位移(间隙)、相对速度和相对加速度反馈两种控制方案的特点,给出了不同车速不同梁跨条件下的悬浮间隙变化的仿真结果,为今后的悬浮控制系统设计、线路设计和施工提供参考。

Suspension Controller Design of Maglev Train Considering the Rail Track Periodical Irregularity

The low speed maglev train which will be used in Badaling traveling line is regarded as the research object. On the basis of building the model of maglev control system and by analyzing the reciprocity between the maglev train and the rail, the designation of maglev train controller under the periodical irregularity of the rail is discussed. Two control schemes are also compared in this paper, one of which uses the relative displacement, the absolute velocity and the absolute acceleration as the feedback, the other uses the relative displacement, the relative velocity and the relative acceleration. The simulation results under different velocity and different bridge span are given in order to provide reference to the designation of the maglev control system and to the designation and construction of the rail track.
