Abstract

The invention provides a magnetic suspension bearing control parameter adjusting method and device, a storage medium and a controller, and the method comprises the steps: obtaining the current operation frequency of a magnetic suspension rotor of a motor by collecting a rotor displacement signal when the magnetic suspension motor stops; and according to the obtained current operation frequency ofthe magnetic suspension rotor, performing self-adaptive adjustment of control parameters of the magnetic suspension bearing. According to the scheme provided by the invention, the operation stabilityand reliability of the magnetic suspension rotor can be improved.

Description

technical field [0001] The invention relates to the field of control, in particular to a method and device for adjusting control parameters of a magnetic suspension bearing, a storage medium and a bearing controller. Background technique [0002] The magnetic levitation bearing control technology is a technology to stably suspend the magnetic levitation rotor at the set position by controlling the bearing coil current to generate corresponding electromagnetic force. The motion states of the maglev rotor mainly include static levitation, rotation, and stop rotation. In the three motion states, the shutdown process often crosses the modal frequency, and the rotor operating frequency may not be controlled during the shutdown process, that is, the bearing controller cannot obtain the current rotor operating frequency, and the accuracy may be poor when crossing the modal frequency In some cases, or when the rotational speed drops to a low state, the rotor precision becomes poor ...
