在静止和低速时，需要信号注入方法来估计永磁同步电机（PMSM）的转子位置。因此，通常检查基于电阻或电感的显着性。虽然后一种情况下，可以找到最文献中，它是可能的，可以通过利用两个显着性在同一时间，而不是评估只有一个的位置信息，以提高无传感器的性能。因此，本文提出了一种改进的位置估计方法，它结合了基于电阻和电感的显着性。基于永磁同步电机的测量结果，新方法进行了比较，单一的电阻和电感为基础的凸极跟踪。
At standstill and low-speed, signal-injection methods are required to estimate the rotor position of a permanent magnet synchronous machine (PMSM). Therefore, usually either the resistance- or inductance-based saliency is examined. Although the latter case can be found most in literature, it is possible that the sensorless performance can be improved by exploiting the position information of both saliencies at the same time instead of evaluating only one of both. Therefore, this paper proposes a modified position estimation method which combines both the resistance- and inductance-based saliency. Based on measurement results of a PMSM, the new method is compared to the sole resistance- and inductance-based saliency tracking.
