| Abstract: | The theory of the torque control in the vector control system is analyzed, then its working principle is demonstrated in detail. The relationships between the output torque and tile rotor parameters are deriwlted them＇ectically. The effect of rotor resistance, rotor inductance and rotor time constant to the stability time, overshoot, precision and the ripple of the output torque are analyzed ihrough simulation. Finally the effectiveness of the theory and the simulation are verified by the experiments, which help to improve the various pe~ormance of the torque control and has strong engineering practical significance. |
