中低速磁悬浮列车牵引控制系统的设计

设计了一套适合中低速磁悬浮列车自身特点的牵引控制系统,采用恒转差频率的方法,消除法向力对列车悬浮稳定性的影响。用交叉感应回线的方式进行测速定位,为悬浮控制系统提供精确的速度、位置信号。改进了传统的PID算法,实现了列车无超调的转速控制,保证了速度位置曲线控制的可行性,使列车具有自动驾驶和准确的站点停靠功能。

Design of tractive control system for mid-low speed mag-lev train

A tractive control system is designed,which adapts mid-low speed mag-lev train.Adopted constant slip frequency for avoiding the effect of the normal force.Detecting speed-position through inductive line interse-cted,which provides signal of speed and position to the tractive control system.The traditional PID control is improved,a nil overshoot speed control is realized,the feasibiliy of control for speed-position curve is ensured,the function of automatic transmission for trains and parked where they want is realized.
