Wind Turbine Tower Thickness and Blade Pitch Control Co-Design Optimization
Résumé
Wind energy production is still a challenge, and improving the engineering practices in wind turbine design is crucial to overcome it. In a control co-design approach, as opposed to sequential design, one considers the interaction between subsystems and applies control concepts in the design process to obtain an optimal solution. This paper investigates control co-design optimization of a wind turbine blade and tower, where the power efficiency is aimed to be maximized while minimizing the system's total mass. Furthermore, bounds on the design parameters are defined to constrain structural loads to admissible values. The power efficiency can be improved by reducing the root mean squared value of the generator speed tracking error, and the mass can be modified by the tower thickness. A mixed control architecture of ∞ and reference governors is proposed to design the wind turbine control system. The ∞ technique reduces structural loads, and the use of reference governors improves the system's power efficiency and addresses actuator limitations. Finally, the benefits of the control co-design optimization method are shown.
