Short summary
The variation in wind speed over the rotor plane causes oscillations in the blade, leading to fatigue damage. These oscillations can be reduced with individual pitch control (IPC), at the expense of more blade actuation. This work proposes two output-constrained IPC methods to facilitate the trade-off between load reduction and actuation increase. Both methods can smoothly transition between conventional full IPC action and no IPC action.
