A wind shear estimation method based on the pitching moment, which acts to overturn a tower along a wind direction, measured at the top of the tower is proposed. We construct wind shear estimation models (WSEMs) using surrogate models whose input is a time-averaged pitching moment and various measurement data (e.g., wind speed). Using simulation data, we construct 20 WSEMs with various input combination and surrogate methods to select a model with the highest accuracy. Subsequently, the best WSEM is applied to a real turbine to validate its accuracy in real wind condition.
