| Abstract: | Maglev train is a new vehicle without support wheel and its movement speed is gained by means of a special measure equipment.By using BP neural network arithmetic,the maglev train speed can be estimated by means of combining characteristics of its traction linear induction motor.Based on a dynamic simulation experiment,real speed measure result is near to theory calculation.This shows the method is feasible.In view of the method,it can economize expensive cost for speed measurement of maglev train,reduce system equipment complexity,and also advance work reliability of entire train system. |
