The voltage equation of the synchronous reluctance motor and the flux observation model of the synchronous reluctance motor were studied.An adaptive observer of the motor speed and angle were designed to detect the angular velocity and position information of the synchronous reluctance motor.The vector control model of synchronous reluctance motor was established by MATLAB simulation,and the accuracy and robustness of the flux observer were verified by simulation under the condition of changing the speed and load of the motor and the inductance of d-q axis.The experimental results showed that the sensorless control strategy proposed could realize efficient and stable control of synchronous reluctance motor.
