Abstract EN
Modern control techniques can improve the performance and robustness of a rotor active magnetic bearing (AMB) system.
Since those control methods usually rely on system models, it is important to obtain a precise rotor AMB analytical model.
However, the interference fits and shrink effects of rotor AMB cause inaccuracy to the final system model.
In this paper, an experiment based model updating method is proposed to improve the accuracy of the finite element (FE) model used in a rotor AMB system.
Modelling error is minimized by applying a numerical optimization Nelder-Mead simplex algorithm to properly adjust FE model parameters.
Both the error resonance frequencies and modal assurance criterion (MAC) values are minimized simultaneously to account for the rotor natural frequencies as well as for the mode shapes.
Verification of the updated rotor model is performed by comparing the experimental and analytical frequency response.
The close agreements demonstrate the effectiveness of the proposed model updating methodology.
