Abstract
Floating offshore wind turbines (FOWTs) are the next great frontier in the offshore energy world. However, for these machines to be safe, effective, and reliable, they must be stable. In this thesis, an active control strategy is developed that uses future wave information and model predictive control to attenuate wave induced motions of a floating platform, such as a FOWT. The future wave information is provided by a wave reconstruction and prediction (WRP) algorithm which allows for wave events to be calculated faster than real-time. This wave information is provided to a nonlinear model predictive controller (NMPC) that uses a digital twin to estimate the disturbance response then calculates the optimal control measures. Previously conducted simulation results illustrated the potential for NMPC to be used in conjunction with WRP to effectively control the motions of a floating platform. The work of this thesis is to experimentally validate those previously developed methods.
