本研究旨在改善感应电动机无速度传感器直接转矩控制（DTC）的性能，特别是在低速和零速运行。为了这个目的，定子电阻的估计是使用扩展卡尔曼滤波器的估计器，它也执行的定子磁通，角速度和负载转矩的估计。仿真结果表明，该算法具有良好的性能和鲁棒性。
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.
