本文提出了一种改进的方法，用于感应电动机驱动器的速度和转子位置估计。一种改进的INFORM方法被用来激励由饱和和转子开槽产生的电机中的磁凸极，由此可以导出位置信号。提出了一种消除位置信号二阶饱和效应的新方法。该方法显著地提高了转子位置估计的质量，使得它可以用于30 kW感应电机的间接转子磁通矢量控制，但不需要在控制器内存储大量的查找表。这种“低内存”方法适用于星星和三角形连接的机器。实验结果表明，无传感器控制的转子速度和位置的跟踪
This paper presents an enhanced method for both speed and rotor position estimation in induction motor drives. A modified INFORM method is used to excite magnetic saliencies in the motor created by saturation and rotor slotting, from which position signals can be derived. A new method is proposed for the elimination of second order saturation effects from position signals. This method significantly improves the quality of the rotor position estimate such that it can be used for indirect rotor flux vector control of 30 kW induction machine, but does not require extensive look-up tables stored within the controller. This "low memory" approach is suitable for both star and delta connected machines. Experimental results for the shaft sensorless control showing the tracking of rotor speed and position are presented
