Abstract

This paper gives a view about a standardized implementation of a combined INFORM/EMF-model to cover the full speed range of sensorless permanent magnet synchronous motor drives. A special feedback loop returns the output information of the observer to the integrating voltage model. Thus, a stable operation with high robustness against parameter uncertainties and low frequency disturbances is achieved.
