摘要：

The use of the EKF for induction machine sensorless control is revisited with focus on the improvement of the method for low speed operation. An appropriate discretization method is discussed, the converter non-linearities are compensated for and the observer includes stator resistance estimation. Sensorless speed closed loop experimental results show stable operation down to standstill in motoring and stable transition through zero frequency in any mode of operation. Limitations are observed for permanent operation near or at zero frequency in regenerative operation, consistent with well known theoretical limitations.
