Abstract :
This paper investigates the minimum requirements to implement compensation schemes for saliency based sensorless control schemes that will work successfully irrespective of the method or machine type. The paper focuses on analyzing the saliency disturbance components due to the machine only, by simulating a machine with a FEM model, and coupling this to a simulation of a full sensorless control which uses ideal power electronic components. The initial results show common saliency harmonics which can therefore simplify the setting up of the filters used to clean up position estimates in sensorless drives.
