Abstract

The present invention provides a method, device, storage medium and controller for adjusting control parameters of a magnetic suspension bearing. The method includes: when the magnetic suspension motor is shut down, the current operating frequency of the magnetic suspension rotor of the motor is obtained by collecting the rotor displacement signal; The acquired current operating frequency of the magnetic suspension rotor performs adaptive adjustment of the control parameters of the magnetic suspension bearing. The solution provided by the invention can improve the stability and reliability of the operation of the magnetic levitation rotor.

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 ...
