Individual Blade Pitch Control Design for Load Reduction on Large Wind Turbines

摘要

The article discusses different design approaches for individual blade pitch control for wind turbines regarding design methodology and robustness aspects. An H, based multi objective control design will be worked out in detail, showing the potential to actively increase damping of the first axial tower bending mode and to reduce 1p fluctuations in blade root bending moments. The control design is verified by simulations with a full nonlinear model of the wind turbine.
