Low Speed Estimation in Sensorless Direct Torque Controlled Induction Motor Drive using Extended Kalman Filter
2015
International Journal of Power Electronics and Drive Systems
Sensorless Direct Torque Control (DTC) is a powerful control scheme for high performance control of induction motor (IM) drives, which provides very quick dynamic response with simple structure and a decoupled control of torque and flux. The performance of the DTC drive depends greatly on the accuracy of the estimated flux components, torque and speed, using monitored stator voltages and currents. Low speed estimation is a great challenge because of the presence of transient offset, drift and
