The invention provides a suspension control method and system for a magnetically levitated train. The method comprises the steps that: the suspension gap value of the magnetically levitated train is collected in real time; and if the suspension gap value is within a suspension control adjustment interval, a suspension control strategy corresponding to the suspension control adjustment interval is executed, the suspension control adjustment interval at least comprises an interval formed by numerical values not smaller than a first threshold value and/or an interval formed by numerical values not larger than a second threshold value, the first threshold value is larger than the preset suspension gap value, the second threshold is smaller than the preset suspension gap value, the first threshold is used for judging whether to execute a suspension control increasing strategy, and the second threshold is used for judging whether to execute a suspension control decreasing strategy. Judgment is carried out based on the suspension gap value, collected in real time, of the magnetically levitated train, and when the magnetically levitated train is in the suspension control adjustment interval, the magnetically levitated train is controlled by executing the suspension control strategy corresponding to the interval, so that the aim of solving the suspension instability condition of the magnetically levitated train without landing the magnetically levitated train is achieved.

    本申请提供一种磁悬浮列车的悬浮控制方法和系统,实时采集磁悬浮列车的悬浮间隙值;若悬浮间隙值处于悬浮控制调整区间内,执行所处悬浮控制调整区间所对应的悬浮控制策略,悬浮控制调整区间至少包括由不小于第一阈值的数值构成的区间,和/或由不大于第二阈值的数值构成的区间,第一阈值大于预设悬浮间隙值,第二阈值小于预设悬浮间隙值,第一阈值用于判断是否执行悬浮控制增大策略,第二阈值用于判断是否执行悬浮控制减小策略。基于实时采集的磁悬浮列车的悬浮间隙值进行判断,在其处于悬浮控制调整区间内,通过执行与该区间对应的悬浮控制策略对磁悬浮列车进行控制,从而实现无需降落磁悬浮列车,解决磁悬浮列车出现悬浮失稳情况的目的。
