A Review on Hysteresis in Magnetic Bearing-Rotor System
There are inevitably hysteresis phenomena in magnetic bearing-rotor systems.On the one hand,the nonlinear relationship of the restoring force and deformation of the engineering materials,especially composites and internal friction between the rotor components may result in hysteresis.On the other hand,there is inherently magnetic hysteresis in the actuator.The hysteresis is a typical one of nonlinear characteristics.The property may have a strong effect on the stability of systems,and make system exhibit complex,unpredictable nonlinear behaviors.It is crucial to analyze magnetic bearing-rotor system by taking account of hysteresis.In this paper,the literature about the magnetic bearing-rotor system with hysteresis are reviewed.The characteristics of nonlinear systems with hysteresis and the effects of hysteresis on systems dynamics are summarized.The modeling approaches are researched and the advantages and disadvantages of each method are pointed out.This paper introduces various methods applied to nonlinear systems with hysteresis and illustrates corresponding results.The methods which could be appropriate for magnetic bearing-rotor systems subjected to hysteresis are discussed and the future research directions have been prospected.
