Dynamic induction control is a wind farm ow control strategy that utilises wind turbine thrust variations to accelerate breakdown of the aerodynamic wake and improve down stream turbine performance. However, when oating wind turbines are considered, additional dynamics and challenges appear that make optimal control di cult. In this work, we propose an adjoint optimisation framework for non-linear economic model-predictive control, which utilises a novel coupling of an existing aerodynamic wake model to oating platform hydrodynamics. Analysis of the frequency response for the coupled model shows that it is possible to achieve wind turbine thrust variations without inducing large motion of the rotor. Using economic model-predictive control, we nd dynamic induction results that lead to an improvement of 7% over static induction control, where the dynamic controller stimulates wake breakdown with only small variations in rotor displacement. This novel model formulation provides a starting point for the adaptation of dynamic wind farm ow control strategies for oating wind turbines.
