Control algorithms for a fault-tolerant PMSM drive
Artikel i vetenskaplig tidskrift, 2007
This paper proposes control algorithms for a fault-tolerant
permanent-magnet synchronous motor (PMSM) drive. In order to improve the reliability of the drive, an algorithm for achieving sensorless control that operates properly also in
fault mode is proposed. Furthermore, it is shown how a closed-loop field-weakening controller needs to be modified in order to operate properly in fault mode. Automotive application in mind and and the algorithms presented are
verified with experimental results using an in-wheel PMSM.
With the proposed modifications, the reliability of the drive can be improved.
