Embodiment Construction
[0043] For the rotor in the magnetic suspension bearing, when it is in the levitation state, it has its own geometric center axis, and when it is in the rotation state, the magnetic field force generated by the stator coil and the load generated by the load make the rotor also have an inertial rotation axis . Ideally, the geometric center axis of the rotor and the axis of inertial rotation should coincide, in which case there is no vibration in the rotation of the rotor. However, due to the problem of process accuracy, the inertial rotation axis and the geometric center axis often do not coincide, which causes the rotor to swing back and forth between the inertial rotation axis and the geometric center axis during the rotation process, which eventually causes the rotor to produce more violent vibration.
[0044] At present, in the process of controlling the vibration of the magnetic suspension bearing rotor, the control signal for controlling the suspension of the rotor is ma...

The invention discloses a magnetic suspension bearing rotor vibration control method, which comprises the steps of: acquiring a rotor displacement signal through using a displacement sensor in a magnetic suspension bearing; extracting a rotor vibration component according to the rotor displacement signal, and determining a displacement feedback signal according to the rotor vibration component; and according to the displacement feedback signal and a preset magnetic suspension reference signal, acquiring a control signal for controlling the rotor in the magnetic suspension bearing to suspend, so s to control the rotor to vibrate according to the control signal. When the rotor vibration is controlled, the rotor speed does not need to be detected, the rotor vibration can be controlled only according to the rotor displacement signal measured by the displacement sensor, the difficulty of controlling the rotor vibration is simplified to a certain extent, and the precision of controlling therotor vibration is improved. The invention further provides a magnetic suspension bearing rotor vibration control device, magnetic suspension bearing rotor vibration control equipment and a computer readable storage medium, which have the above beneficial effects.
Description
technical field [0001] The present invention relates to the technical field of magnetic suspension bearing rotor control, in particular to a magnetic suspension bearing rotor vibration control method, device, equipment and computer-readable storage medium. Background technique [0002] Magnetic suspension bearing is a high-performance bearing that uses magnetic field force to suspend the rotor in the air without mechanical friction. It can realize active control and has the characteristics of high speed, no mechanical friction and no lubrication. It is widely used in fans, compressors, Water pumps, high-speed motors, high-speed expansion / steam generators, various high-speed milling and cutting machine tools, flywheel energy storage devices, vacuum environments and dust-free and sterile fields. [0003] Due to machining errors, uneven geometric distribution of material quality, etc., the rotor of the magnetic suspension bearing must have the problem that the inertia axis, geo...
