Individual/collective blade pitch control of floating wind turbine based on adaptive second order sliding mode

A new control strategy based on adaptive second order sliding mode approach is applied to a floating wind turbine system in the above rated region. This controller well adapted highly nonlinear as turbine, and can be easily implemented with very reduced knowledge of modeling. The proposed partially multi-blade coordinates transformation combines collective individual blade pitch control, for power regulation, platform motion reduction blades fatigue load. FAST simulator shows high level performances.
