Vibration control method for full-rotation-speed magnetic suspension high-speed motor rotor

The invention discloses a full-rotation-speed magnetic suspension high-speed motor rotor vibration control method, which comprises the following steps: determining a system lag phase under a full rotation speed through a frequency sweeping method, and further obtaining a curve of the lag phase changing along with the rotation speed under the full rotation speed; secondly, filtering is carried out through an LMS algorithm, phase shift compensation is carried out according to a lagging phase curve, and an obtained signal phase serves as an unbalanced vibration control signal phase; then, obtaining control signal amplitudes of the rotor system at different rotating speeds through an influence coefficient method, and performing fitting to obtain a curve that the full-rotating-speed control signal amplitudes change along with the rotating speeds; and then, according to the phase curve and the amplitude curve, unbalance compensation is carried out in the speed increasing and reducing process of the rotor, and motor
