| Abstract |
The paper presents the main features of the Zero Sequence Technique (ZST), a sensorless algorithm
able to work at low and zero speed with full torque capability. The proposed method is different in
principle than any other sensorless technique and much simpler on the implementation aspects,
although it still belongs to the class of air gap flux estimators. A distinctive characteristic of the
approach is that it also allows us to detect the amplitude of the air gap flux, thus exploiting full flux
sensing capability not limited to only flux position estimation. Experimental and Finite Element
Analysis results validate the performance of the method in comparison with standard sensorless
techniques based on detecting the amplitude variation of high frequency currents. |
