... of the following steps; this give the chance to modify the undertaken path in order to follow the incoming input. The wave energy converters (WECs) do not distinguish themself for this basic idea, they need the knowledge of a portion of future in order to get the maximum output, (Falnes, 2002). If we glance...

... unit mass in irregular waves is found to admit a maximum at a fixed buoy height-to-radius ratio. INTRODUCTION It is a well known fact (Falnes, 2002) that the theoretical maximum power that can be absorbed from an axisymmetric body oscillating in heave or pitch only is limited by the energy transport...

... control strategies depends, among other issues, on the prediction of future wave elevation or wave excitation force acting on the system at least for a few seconds (Falnes, 2007). hankel singular value approximation frequency excitation force transfer function sustainable development...

... others—for producing electricity from ocean waves. Of special interest in this article are wave-energy devices that can be categorized as point absorbers. A point absorber (Budal & Falnes, 1975; Falnes, 2002) can be defined as a relatively small, damped mechanical oscillator excited by ocean surface...

..., an axisymmetric heaving body was considered as a means for extraction of wave energy (McCormick, 1974; Ambli et al., 1977; Bergdahl et al., 1979; Budal & Falnes, 1980; Hicks & Pleass, 1986; Hopfe & Grant, 1986; Nielsen, 1986). If a piston pump is connected between the body and some forceresisting...

.... On the other hand, an advantage with point absorbers is that the smaller the structural volume of the converter is, the larger is the ratio between the potentially converted power and the mentioned volume (Budal & Falnes, 1980). Hence, for a point absorber it is imperative that means are provided...

One approach to such control is frequency domain "adjustable tuning" to increase the energy ab- sorption in wave spectra other than those with peak frequencies close to the device resonant...
