A method of estimating an amount of undesired loading experienced by at least a portion of a structure () is provided. The structure () may be, for example, a wind turbine generator (WTG) and the portion for which undesired loading is estimated may be, for example, a rotor () of the WTG. The method includes receiving a first signal characterizing instantaneous stress experienced by a component () of the structure () and filtering out at least a portion of the received first signal that corresponds to the desired loading experienced by the component to produce a first filtered signal. The amount of undesired loading experienced by the at least a portion of the structure () is estimated based at least partially on the first filtered signal.
