Model based analysis and identification of unbalance and misalignment in rotor systems levitated by active magnetic bearings

Abstract

The work presented in the thesis emphasizes mainly on the simultaneous identification of unbalance and misalignment faults as well as AMB stiffness parameters in a magnetically levitated rigid and flexible rotor system using a novel trial misalignment approach with model based identification algorithm The proposed approach is aligned with the similar concept of trial unbalance in the rotor balancing In real practice the known trial misalignment between the rotor operating axis and AMBs axis c...
