Combined Lidar-based feedforward and feedback controllers for wind turbines with tower and blade damping

Two advanced controllers designed to reduce wind turbine component loading have been developed in this paper. The advanced controllers attempt to damp tower fore-aft and blade root bending moments using tower fore-aft and blade flap tip signals in feedback to augment the commanded pitch angle of the baseline controllers. Three baseline controllers are considered in this study: a PI feedback only collective pitch controller, a combined feedback/feedforward collective pitch controller, and a combined feedback/feedforward individual pitch controller. Simulation results in realistic turbulent wind fields demonstrate that adding fore-aft tower damping and blade damping to standard baseline controllers can give effective mitigation on the tower fore-aft and blade flapwise bending moment without reducing power production.
