This paper proposes the application of a Bayesian method that accounts for model discrepancy to the rotor imbalance identification problem. Compared to Bayesian approaches that do not account for discrepancy, the methodology in this paper results in more accurate estimates of imbalance and associated uncertainty estimates.
