초록
This paper proposes a control method of induction machine at a low speed range. When an encoder is used for speed detection, we usually obtain speed information from the increased pulse number. At low speed range, however, we can get only average speed between encoder pulses and it makes speed controller unstable. By using a disturbance observer and torque current, it is possible to estimate accurate speed information. The simulation and experiment show that the stable speed control is performed at a low speed with proposed algorithm.
