Abstract
In this work, a new control strategy has been proposed to improve the stability of floating wind turbines (FWT). In order to study the reduction of undesired oscillations in the system, and in particular in the platform pitch and fore-aft nacelle movements. A square-shaped barge-type platform has been considered and equipped with four symmetrically located Oscillating Water Columns (OWCs). In this way, the air flow control valves of the capture chambers allow the aforementioned air columns to be operated so that to control the movements of the barge caused by the oscillatory dynamics of the incident wave. To do so, an analysis of the response amplitude operators (RAO) has been carried out, which in turn allows the implementation of a new switching control strategy to properly regulate the transition of the flow control valves. The results obtained show that the proposed hybrid platform topology, equipped with OWC controlled systems, presents better performance than a traditional analog platform.
