Abstract

This work deals with the identification of non-stationary/time-dependent dynamics based on vector measurements by means of postulated Linear Parameter Varying Vector AutoRegressive models, applied to the identification of the vibration response of an operating wind turbine blade. The focus here lies in estimation of the model parameters and their corresponding covariances, as well as the calculation of “frozen” modal quantities from identified models. The proposed methodology is verified on a simulated case study, consisting of an operational wind turbine blade.
