Hierarchical Control Co-Design for the Development of Floating Vertical-Axis Wind Turbines

by

The objective of this project is the development of a hierarchical control co-design (H-CCD)
formulation, specifically applied to the floating vertical-axis wind turbine (FloatVAWT) system
design as a strategy to enable achievement of aggressive LCOE targets. Vertical-axis wind
turbines (VAWTs) have significant potential in achieving low-cost floating offshore wind turbine
(FOWT) systems based on their inherent characteristics favorable to the marine environment
because they have lower vertical centers of gravity and aerodynamic pressure, demanding
smaller and less expensive floating platforms.
