Abstract: | 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. |
