Sensorless control techniques of ac machines based on fundamental wave methods have a critical point of operation at zero frequency. Using signal injection methods zero frequency operation is possible, however another critical point of operation may exist at overlap frequencies which, so far has not been addressed by research. The resulting signals from injection based sensorless control methods are composed of components caused by saturation, slotting or anisotropy saliencies, as well as inter… CONTINUE READING
