Abstract
Performance of direct torque control (DTC) system at low speed is so poor that it is easy to vibrate. This paper concludes that it is because of phase errors of estimated stator flux. A simple method is proposed to improve it by tuning flux phase according to current phase. Experiments show it feasible and promising in the final part
