A control system for calibrating a wind turbine sensor placed on a component of a wind turbine and related methods are disclosed. The wind turbine includes a rotor having at least one wind turbine blade. The method comprises pitching one or more of the at least one of the wind turbine blades according to a predetermined pitch movement which induces a vibratory motion in the at least one turbine blade. A wind turbine sensor measures a vibratory response signal at least partly caused by the vibratory motion. A characteristic sensor response value is determined from the vibratory response signal. The characteristic sensor response value may be compared to a predetermined sensor calibration parameter to determine whether a difference is greater than a predefined tolerance parameter. In this manner, the wind turbine sensor may be calibrated.
