本文分析了感应电机中饱和诱发显著性的来源和行为，以及它们对基于载波信号注入的无传感器技术的影响。磁链位置的估计需要对饱和诱导的显著性进行建模，而转子位置的估计则需要最小化它们的影响。特别关注转子位置估计，有两种方法来实现这种最小化，第一种是使用机器设计来减少不希望的饱和诱导显着性的大小，第二种是在不希望的饱和诱导显着性的估计器中进行补偿。本文讨论了饱和引起的显著性的建模，不仅是静态的，而且是动态的，即当机器的工作点发生变化时。
This paper analyzes the origin and the behavior of saturation-induced saliencies in induction machines, and their influence on carrier signal injection based sensorless techniques. The modeling of saturation-induced saliencies is necessary for the estimation of flux position, while the minimization of their influence is desired for the estimation of rotor position. Specifically focusing on rotor position estimation, there are two ways to achieve this minimization, the first being the use of a machine design that reduces the magnitude of the undesired saturation-induced saliencies and the second being the compensation in the estimator of the undesired saturation-induced saliencies. The modeling of saturation-induced saliencies, not only statically, but also dynamically, i.e. when the operating point of the machine changes, is addressed by this paper.
