The overall objective of the project is to enhance the knowledge and develop advanced methods and tools for the research and development of unsteady aeroelastic control concepts for multi-MW wind turbine rotors. The focus is on the development of deeper understanding of the unsteady aerodynamics phenomena in combination with the operation of the distributed load control devices in wind turbines and on the evaluation of the benefits of using advanced models and controllers in the predictions of aeroelastic simulations. From the present stage of proven concepts, and first order numerical and experimental predictions, the project will contribute to the development of the research field to a new stage where it constitutes a complete, reliable and robust approach to system design, which is ready for prototype testing, with the target towards lowering the cost of energy produced by modern large-scale wind turbines. This will further strengthen the knowledge transfer and integration in the research field and enhance the collaboration between relevant research institutes.
