Abstract

This paper presents a sensorless vector control technique for synchronous reluctance motors. The rotor position is calculated easily from ds-qs axes flux linkages which are estimated with a first-order lag compensator. Furthermore, utilizing estimated rotor position as the input of the full-order observer, the rotor speed and disturbance torque are estimated. The proposed sensorless vector control scheme is demonstrated with experimental results
