Abstract
The elimination of the position sensor has been one important
requirement in vector control systems because the position sensor spoils
the reliability and simplicity of drive systems. Therefore, we present 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
