Abstract:

This paper proposes an enhanced method to represent the rotor position to control a Permanent Magnet Synchronous Motor (PMSM) based on a First-Order Taylor-Series approximation, by using misplaced Hall-effect switch sensors. The main feature of this algorithm is the speed estimation from two consecutive edge-transitions of a single phase. Furthermore, when a new electrical cycle starts, a compensation algorithm assists this method to achieve error cancellation in the electrical angle representation. Simulation results with an Interior Permanent Magnet Synchronous Motor (IPMSM) verify the effectiveness of the proposed method showing less than 0.5% error in the angle estimation and less than 2% in terms of harmonic content.
