Feedback linearisation control applied to the Archimedes Wave Swing

Feedback linearisation control is, to the best of the authors´ knowledge, applied for the first time to a wave energy converter (WEC), the Archimedes Wave Swing, a WEC of which a 2 MW prototype has already been tested in Portugal. A sevenfold average increase in absorbed wave energy over the situation without any control strategy is attained in simulations. This control strategy is thus recommendable and seems to be important to ensure economic viability.
