Single-freedom magnetic liquid dual-suspension bearing control system

Abstract

The invention discloses a single-freedom magnetic liquid dual-suspension bearing control system, and belongs to the technical field of control. The single-freedom magnetic liquid dual-suspension bearing control system comprises a PD controller and a differential type power amplifier, a magnetic force conversion module and a feedback proportional module which are sequentially connected to form an electromagnetic closed-loop control system, wherein the feedback proportion module is connected to a static pressure conversion module; the static pressure conversion module is simultaneously connectedto a pressure sensor 1 and a pressure sensor 2; and the pressure sensor 1 and the pressure sensor 2 are arranged on upper and lower supporting cavities of a single-freedom magnetic liquid dual-suspension bearing body. A metering pump, an overflow valve, a one-way valve, a filter, a PM flow controller and the single-freedom magnetic liquid dual-suspension bearing are sequentially connected to forma static-pressure control system. The single-freedom magnetic liquid dual-suspension bearing control system provided by the invention is great in regulating ability, is quick in response, is good indynamic characteristic, and greatly improves stability of magnetic liquid dual-suspension bearing operation.

Description

technical field [0001] The invention belongs to the technical field of control, and in particular relates to a single-degree-of-freedom magnetic fluid double-suspension bearing control system. Background technique [0002] The magnetic fluid double suspension bearing is a high-performance electromechanical integrated bearing that uses electromagnetic force to stably suspend the supported part in space. The magnetic fluid double suspension bearing includes two sets of support systems: electromagnetic support and static pressure support, while the traditional control method is single and the recovery response speed is slow. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a single-degree-of-freedom magnetic-fluid double-suspension bearing control system, which improves the bearing capacity and response speed of the magnetic-fluid double-suspension bearing by real-time outputting the proportional relationship between...
