A magnetic levitation system and its control method, device, storage medium and processor

Abstract

The invention discloses a control method and device for a magnetic suspension system, a magnetic suspension system, a storage medium and a processor. The method includes: when the compressor of the magnetic suspension system is installed, obtaining the axial reference displacement of the bearing of the magnetic suspension system as The initial axial reference displacement of the bearing; when the compressor of the magnetic levitation system is turned on, the axial displacement detection of the bearing of the magnetic levitation system is carried out to obtain the current axial reference displacement of the bearing; according to the current axial reference displacement and the initial axial reference displacement to determine the difference between the current axial air gap of the bearing of the magnetic levitation system and the axial air gap during installation; according to the difference between the current axial air gap and the axial air gap during installation, the The bearings of the magnetic levitation system perform axial control. In this scheme, the bearing axial control of the magnetic suspension bearing is realized through the axial reference displacement of the magnetic suspension bearing and the axial bearing coil current, which can improve the safety of the operation of the magnetic suspension bearing.

Description

technical field [0001] The invention belongs to the technical field of magnetic suspension bearings, and in particular relates to a control method, device, magnetic suspension system, storage medium and processor of a magnetic suspension bearing, and in particular to a method for realizing an axial control strategy of a magnetic suspension bearing, a device, a magnetic suspension system, and a storage device. media and processors. Background technique [0002] In the related scheme, the axial control strategy of the magnetic suspension bearing is to use the oil resistance sleeve as the axial displacement detection surface, and reflect the axial displacement change through the displacement change of the oil resistance sleeve, so as to realize the control of the axial displacement of the rotor. However, due to the manual assembly of the oil blocking sleeve, there are many uncertain factors such as assembly errors and process errors, which lead to the displacement of the oil bl...
