Research of Force Feedback Controlling on High Speed Maglev Train Guidance System

To improve the performance of the guidance system, the key system of maglev train, a force feedback controlling method is researched. First of all, the model of the guidance system on EMS high speed maglev train is set up, and the classical designing method is introduced. Then, in order to improve the dynamic stiffness of the guidance system, a new controlling method by the combination between force feedback and gap feedback is put forward. The force feedback is used to meet the rapid change of disturbance; meanwhile, the gap feedback is used to meet the gap change. Through simulation, this controlling strategy is proved to be right and very effective to ensure guidance system´s good and stable operation.
