Model based fault and system parameter identification in rotor amb systems with breathing crack

Abstract

Active Magnetic Bearings AMB find applications in new generation rotating machines due to their versatilities In context of AMB the literature is rich on two aspects first research on control strategy to ensure stability and second design of forcing to extract information about condition of the rotor shaft The available literature does not include the problem of crack identification in rotor supported with AMB sustentation In the present work model based detection of a relatively sm
