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 ...
