This paper discusses the position sensorless control of a salient-pole synchronous-reluctance machine
(SynRM) whose performance is analysed. Depending on the rotational speed of the machine different
methods have to be applied. At low-speed range the INFORM method is used, which is based on the
magnetic anisotropy of the rotor. At high-speed range two different methods are implemented and compared. The first method is the Back-EMF model, which is based on the flux estimation by integrating
the induced voltage. The second method, the short-circuit method, directly uses the measured electrical
quantities to calculate the rotor position. No further integration or other dynamical operations are necessary, which increases the dynamic of the position sensorless control model. These mentioned position
sensorless control methods were implemented and tested on a prototype to verify the performance of
each algorithm.
