Abstract :
The work developed in this paper shows the features offered by a novel PLL scheme in order to realize an observer-based full-sensorless strategy for a Permanent Magnet Synchronous Motor drive. It will be explained how the presented scheme enables to easily overcome the problems linked to speed reversals characterizing other conventional Phase-Locked Loop schemes. A detailed analysis of the algorithm will be given and the integration with the overall scheme will be presented. The major differences with standard solutions will be highlighted too.
