Research on Speed Identification of Vector Control System of Bearingless Induction Motor Based on Improved MRAS
摘要
Abstract
Based on the improved voltage model rotor flux,a speed sensorless vector control of bearingless induction motor was constructed based on rotor-flux orientation.MATLAB/Simulink simulation results show that the improved voltage model rotor flux proposed improves the observation accuracy of the rotor flux.At the same time,based on the speed sensorless vector control of bearingless induction motor oriented by rotor-flux,the identified speed and the measured speed has a good consistency under the condition of no-load speed regulation and load,and the motor can be stable suspension operation,that verifies the effectiveness of the proposed scheme.关键词
