Résumé
Floating offshore wind turbines suffer oscillations due to external disturbances, mainly waves and strong winds, which in the short-term have been shown to reduce efficiency and in the long-term cause mechanical fatigue. These vibrations can be reduced by using active control. For the design of efficient controllers for these complex and non-linear devices, in this work a model based on transfer functions is developed, along with its identification. Synthetic realistic data have been generated using OpenFAST turbine simulation software. Using data from a 5-MW barge-type floating wind turbine, a six-degree-of-freedom model suitable for control system design is identified. A classical control analysis is carried out for the roll and pitch degrees of freedom of the floating turbine, concluding that the roll requires a co-design of the system, but the pitch does allow effective control. The results obtained with a PD over the blade pitch angle actuator are presented, which will serve as a baseline for the development of other controllers.
