Dynamics Modeling Analysis and Experiment of the Guidance Control System of High-Speed Maglev Train

The guidance control system of the high-speed maglev enable that the maglev can travel along the center line of track. When the maglev passes through curve, the guidance control system also provides guidance force. When the maglev operates on the track, the friction between guidance electromagnet and track happens sometimes. This problem will pose a great threat to the safety of maglev running. However, other studies have failed to reflect the actual operation very well. In order to give a reasonable explanation for problems happened in actual test, the dynamics model of the guidance control system in high-speed maglev is established in this paper. The curve operation simulation was carried out, and the reason of the friction problem was analyzed through the results of simulation. Finally, an actual running test was carried out. The result of test shows that the high-speed maglev guidance control model established in this paper is effective. This model can provide an platform for analyzing the motion of guidance control units of the high-speed maglev train, further provide a model reference for the design and optimization of the control algorithm.
