Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] In recent years, for the control of unbalanced disturbance, the most researched and applied is the adaptive unbalanced compensation algorithm based on LMS (Least mean square algorithm, least mean square algorithm). The LMS algorithm is used to construct the LMS compensator to compensate the unbalanced vibration. LMS Although the compensation algorithm has o...

Abstract

The invention discloses a magnetic suspension bearing control device, a magnetic suspension bearing and a control method thereof. The device comprises a displacement feedback module (5) and a trappedwave unbalance vibration controller (4), wherein the displacement feedback module (5) is used for acquiring displacement information of a magnetic suspension rotating shaft (3) of the magnetic suspension bearing; the displacement information comprises rotary displacement information of rotation around a geometric center of a magnetic suspension rotating shaft (3) and unbalance displacement information of rotation around the centroid of the magnetic suspension rotating shaft (3); and the trapped wave unbalance vibration controller (4) is used for compensating the unbalance displacement information in the displacement information to obtain effective displacement information. By the scheme, the shortcomings of large unbalance disturbance, high control difficulty, poor running stability and the like in the prior art can be overcome, and beneficial effects of low unbalance disturbance, low control difficulty and good running stability are achieved.

Description

technical field [0001] The invention belongs to the technical field of magnetic suspension, and in particular relates to a control device of a magnetic suspension bearing, a magnetic suspension bearing and a control method thereof, in particular to a control device for unbalanced vibration of a magnetic suspension bearing, a magnetic suspension bearing with the device, and an unbalance of the magnetic suspension bearing Vibration Control Methods. Background technique [0002] The magnetic levitation technology is currently developing rapidly. The magnetic levitation shaft runs in an environment without mechanical contact, so it can easily achieve high-speed and ultra-high-speed rotation. figure 1 The illustration is completely coincident. In this ideal situation, when the magnetic levitation shaft is rotating, it always rotates symmetrically with the geometric center as the origin. In this rotating state, the control of the shaft is undoubtedly an extremely ideal state. How...
