摘要

使用EKF的感应电机无传感器控制被重新审视，重点是改进方法的低速运行。讨论了适当的离散化方法，对变换器的非线性进行了补偿，并对观测器进行了定子电阻估计。无传感器速度闭环实验结果表明，在任何工作模式下，该系统都能稳定地运行到静止状态，并稳定地过渡到零频率。在再生操作中，在接近零频率或零频率的永久操作中观察到限制，这与众所周知的理论限制一致。

Revisiting the EKF concept for low speed sensorless control of cage induction motors

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.
