Although there is an abundant wave energy resource available world-wide, and particularly in Ireland, after almost 50 years of research and development no commercially successful technology has been developed. One of the reasons is the limited focus of the research in this area. None of the traditional WECs, which harness buoyancy or diffraction wave forces have shown themselves to be commercially viable. This creates motivation to develop new principles for wave energy extraction. Recently, a lift-based wave energy converter that utilises lift force generated on hydrofoils due to their inter-action with the wave-induced circular motion of water particles, started to attract attention from various research groups. Cyclorotor-based WECs have a number of appealing characteristics, including the potential for unidirectional rotation, simplified power take-off, and reduction of wave loads by adjusting pitch angles, increasing survivability. However, as it has been shown in, the performance of the cyclorotor requires real-time control (especially in panchromatic seas). The reviews of cyclorotor-based WECs have identified the variation of the rotational rate and hydrofoil pitch angle as the most advanced actuators.
