磁悬浮轴承力--电流/位移线性化策略研究综述

摘要

分析了磁悬浮轴承电磁力与其电流和转子位移非线性关系产生的原因，结合国内外文献资料，主要从磁轴承偏置磁场以及本质非线性两方面对磁悬浮轴承力与电流及其位移关系线性化策略进行概述。%The authors of this paper analyzes the causes of the nonlinear relationship between the electromagnetic force of the magnetic bearings and their current and rotor displacement and stud-ies the optimization strategies for the linear relationship between the electromagnetic force of the magnetic bearings and its current and rotor displacement from the aspects of the bias magnetic field of magnetic bearings and their intrinsic nonlinearity,based on domestic and foreign literature.
