Robust Proactive Control of Wind Turbines with Reduced Blade Pitch Actuation
Paper in proceedings, 2013

A new simultaneous speed and pitch control of wind turbines with the preview measurements and look-ahead calculations is considered. The desired piecewise constant pitch angle profile which is calculated using turbine load prediction, allows the reduction of pitch actuation that in turn, increases the lifetime of actuator. The robust collective pitch control architecture with the maximum possible actuation rate is proposed. Moreover, a new postprocessing technique that provides the high quality estimate of the turbine inertia moment is also described. The results are confirmed by simulation with a wind speed record from the Hönö turbine located outside Gothenburg, Sweden.
