Incremental Nonlinear Control for Aeroelastic Wing Load Alleviation and Flutter Suppression

This paper proposes an incremental nonlinear control method for an aeroelastic system’s gust load alleviation and active flutter suppression. These two control objectives can be achieved without modifying the control architecture or the control parameters. The proposed method has guaranteed stability in the Lyapunov sense and also has...

Active aerodynamic load control on wind turbines: Aeroservoelastic modeling and wind tunnel

This thesis investigates particular concepts and technologies that can alleviate fatigue loads on wind turbines by using distributed active aerodynamic devices on the blades, a concept briefly referred to as `smart blades'. Firstly, published research work on smart control devices is reviewed, and the pros and cons for the application on wind...

Controller Design Automation for Aeroservoelastic Design Optimization of Wind Turbines

The purpose of this paper is to integrate the controller design of wind turbines with structure and aerodynamic analysis and use the final product in the design optimization process (DOP) of wind turbines. To do that, the controller design is automated and integrated with an aeroelastic simulation tool. This integrated tool is linked with an...
