ESTIMATING AND CONTROLLING LOADING EXPERIENCED IN A STRUCTURE |
| 摘要 |
A method of estimating an amount of undesired loading experienced by at least a portion of a structure (100) is provided. The structure (100) may be, for example, a wind turbine generator (WTG) and the portion for which undesired loading is estimated may be, for example, a rotor (130) of the WTG. The method includes receiving a first signal characterizing instantaneous stress experienced by a component (140) of the structure (100) 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 (100) is estimated based at least partially on the first filtered signal. |

1. A method of estimating and controlling an amount of undesired loading experienced by at least a portion of a structure, the method comprising:
receiving a first signal characterizing instantaneous stress experienced by a component (140) of the structure; filtering the received first signal to produce a first filtered signal in which at least a portion that corresponds to desired loading experienced by the component is removed; and estimating the amount of undesired loading experienced by the at least a portion of the structure based at least partially on the first filtered signal. |
