Summary:Considering the need of speed sensorless operation for bearingless induction motor, the model reference adaptive method which takes reactive power as reference quantity is used to identify speed for the SVM-DTC system of the bearingless induction motor. The method eliminates the influences of pure integration and rotor resistance. Simulation results show that model reference adaptive control using reactive power as reference quantity can realize the stable suspension and rotation without speed sensor for the bearingless induction motor under the condition of heavy load disturbance. The speed recognition has high accuracy, and the whole control system has good static and dynamic performance.
