摘要：
In order to improve the operating performance of a bearingless induction motor (BIM) based on vector control and increase the rotor suspension accuracy, an improved repetitive control strategy for the BIM was proposed. The BIM suspension system was a multi-variable coupling system in the rotating frame. A simplified model of suspension control system was deduced firstly. Based on the conventional repetitive control, the fractional delay filter and the weighted extended repetitive control internal model were introduced. The robustness of repetitive control to frequency fluctuation was improved, and the stability criterion of the improved repetitive control system was given. The high-precision suppression of vibration caused by rotor mass imbalance was realized. The simulation and experimental systems of the BIM were finally built and compared with conventional repetitive control. The results show that the improved repetitive control strategy for the BIM can effectively suppress the vibration of the rotor in steady state and improve the suspension accuracy of the BIM. © 2019 Chin.
