Abstract
This study aims to improve the performance of the speed sensorless direct-torque control (DTC) of induction motors (IMs), specifically in low and zero speed operation. To this aim, the estimation of the stator resistance is performed using an extended Kalman filter based estimator, which also performs the estimation of the stator flux, angular velocity and load torque. Simulation results demonstrate a good performance and robustness.
