Abstract：A novel sensorless vector control method for induction motor based on two-parameter model reference adaptive is proposed in this paper. The rotor speed and stator resistance could be identified simultaneously, and the impact of stator resistance change at low speed is weakened effectively. The linear small-signal model of speed closed-loop system is derived, and the stability of system and the impact of PI parameter are analyzed. The two-parameter model reference adaptation is verified by the experiment and compared with the traditional adaptive model. The experimental results verify the effectiveness of the algorithm.
