Abstract
Trailing Edge Flaps on wind turbine blades have
been studied in order to achieve fatigue load reduction on
the turbine components. We show in this paper how Model
Predictive Control can be used to do frequency weighted control
of the trailing edge flaps in order to reduce fatigue damage
on the blade root. The design model is based on a modal
model of the blade structure and a steady state aerodynamic
model of the blade airfoils. Depending on the output filter, loads
within different frequency range are decreased. A fine tuning
of the Kalman filter and of the cost function allows to decrease
significantly the blade root loads without damaging excessively
the trailing edge flap actuators.
