This paper deals with the realisation of a minimal sensor drive for a Permanent Magnet Synchronous Motor based on a single DC link current measurement. The reconstruction of line current is obtained from the DC link current information while position and angular speed of the rotor are estimated through an Extended Kalman Filter. The proposed estimation algorithm is merged with a predictive current control, for an effective full-digital implementation of the drive.

Abstract
This paper deals with the realisation of a minimal sensor drive for a Permanent Magnet Synchronous Motor based on a single DC link current measurement. The reconstruction of line current is obtained from the DC link current information while position and angular speed of the rotor are estimated through an Extended Kalman Filter. The proposed estimation algorithm is merged with a predictive current control, for an effective full-digital implementation of the drive.File in questo prodotto:
