| Abstract: | A method of parameter identification based on mutual model reference adaptive system(MRAS) is proposed, rotor speed and stator resistance are independently adapted on-line, which will meet the need of speed sensorless operation for bearingless induction motors. The computer simulation and experimental results show that mutual model reference adaptive control system of bearingless induction motor based on stator flux orientation of motor winding is able to achieve stable speed sensorless suspension operation for bearingless induction motor under the condition of heavy load disturbance and validity of proposed control strategy is proved. |
