Speed sensorless of induction motor with adaptive full order state observer

Abstract Speed sensorless vector control of induction motor not only maintains the excellent performance of vector control, but also overcome the disadvantage of speed sensorless. It can reduce the cost and improve the reliability. So speed sensorless control have been widely researched. The paper implement speed sensorless control by the adaptive full order state observer and give debug process. Experiment results shows that this approach have excellent performance.
