Abstract :
In the paper by Vaclavek et al. ( IEEE Trans. Ind. Electron., vol. 60, no. 8, pp. 3047-3059, Aug. 2013), the local observability of both induction machine and permanent-magnet synchronous machine (PMSM) under motion-sensorless operation is studied. In this letter, the “slowly varying” speed assumption is discussed, and the PMSM observability condition at standstill is revisited.
