AB Floating offshore wind turbines (FOWTs) are systems with complex and highly nonlineardynamics; they are subjected to heavy loads, making control with classical strategies a challenge. Inaddition, they experience vibrations due to wind and waves. Furthermore, the control of the bladeangle itself may generate vibrations. To address this issue, in this work we propose the design ofan intelligent control system based on fuzzy logic to maintain the rated power of an FOWT whilereducing the vibrations. A gain scheduling incremental proportional–derivative fuzzy controller istuned by genetic algorithms (GAs) and combined with a fuzzy-lookup table to generate the pitchreference. The control gains optimized by the GA are stored in a database to ensure a proper operationfor different wind and wave conditions. The software Matlab/Simulink and the simulation tool FASTare used. The latter simulates the nonlinear dynamics of a real 5 MW barge-type FOWT with irregularwaves. The hybrid control strategy has been evaluated against the reference baseline controllerembedded in FAST in different environmental scenarios. The comparison is assessed in terms ofoutput power and structure stability, with up to 23% and 33% vibration suppression rate for towertop displacement and platform pitch, respectively, with the new control scheme. Fatigue damageequivalent load (DEL) of the blades has been also estimated with satisfactory results.
