Operational modal analysis of a spar-type floating platform using frequency domain decomposition method [PDF]

, 2016
System identification of offshore floating platforms is usually performed by testing small-scale models in wave tanks, where controlled conditions, such as still water for free decay tests, regular and irregular wave loading can be represented.

Floating wind turbine control optimization

Journal of Physics: Conference Series, 2022
Abstract We present a framework for optimizing the control parameters of floating offshore wind turbines (FOWTs). The framework combines aeroelastic simulations with a systems engineering model and control software. In an example of the optimization framework, we minimize tower damage equivalent loading with generator speed constraints ...

On the Controllability of a Floating Offshore Wind Turbine

Journal of Physics: Conference Series, 2020
Abstract An analytical method for assessing the controllability of floating offshore wind turbines (FOWTs) is presented in this work. Modern linear control theory principles are applied to linearized FOWT models to establish quantifiable metrics to determine advantageous, or disadvantageous, differences in turbine models from a controls ...
