The operating characteristics and the structure of the bi -axle railway were given .The bi-axle railway was driven by permanent magnetic synchronous motor .Based on principle of vector control , the PI con-trollers of the current loop and the velocity loop based on it were built .The simulation of rotating control was car-ried out in different operating states based on vector control system of PMSM .The results show that the perform-ance of the velocity controlling is excellent when the load ( torsion load ) and running speed change with stochas-tic excitation and the electromagnetic torque of the motor can trace the load very well .The designed control sys-tem can achieve both stability and rapidity .
