Aeroelastic integrated wind turbine control

The potential of future controllers will be identified and design limits will be mapped. As a part of this, individual pitching of each blade based on load response input parameters will be treated, aiming at optimizing the operational state, reducing loads and enhancing stability. The basis of the project is an existing traditional pitch controlled turbine with variable speed. General design tools for controller design using both linear and non-linear aeroelastic methods will be developed. These design tools will be verified using traditional methods, and optimum controller strategies will be developed. As part of this, the necessary changes in the structural and aerodynamic design will be identified, in order to obtain an optimum controller. The design of controller strategies will address the following main principles: 1) Optimising power production with simultaneous load reduction øf the main wind turbine components (gear box, tower, blades). 2) Adaptive control with respect to actual operational conditions
