摘　　要：磁浮列车处于不同轨道曲线上时,系统的数学模型会发生变化,这会影响列车的悬浮性能,从而限制磁浮列车的行驶速度;采用加速度计输出和间隙二次微分组合反馈的非线性控制方法,解决了系统模型变化的问题,消除列车在不同轨道曲线上性能改变的不利影响,保持列车悬浮性能不变;仿真结果验证了所采用的控制方法的有效性。The maglev train system model is different when the train is on different track curve,which will affect the suspension performance and limit the train＇s velocity.The problem of model variability could be settled when the nonlinear control method of accelerometer output and second derivative of gap were obtained and applied to the controls.The disadvantage brought by the track curve variety could be eliminated and the maglev suspension performance is invariable.The validity of the method is proved through simulation at last.
