Optimisation of a wave energy converter.
In: IFAC Conference on Control Applications in Marine Systems - CAMS 2004, July 7-9 2004, Ancona, Italy.
This paper examines a simple model of an idealised point-absorber wave energy device. The objective of the research is to examine how the device can be optimised in order to extract maximum energy from incident waves. This applies to both the broad design parameters of the buoy and also to the synthesis of the damping function, in which the wave energy is converted. The issue of the adjustment of the phase of the velocity evolution with respect to the incident force (known as phase control) is dealt with in detail, with the intention of optimising the damping force over the wave cycle. The research ultimately attempts to parameterise the optimal damping force in terms of incident wave frequency and device parameters.
