A Critical Assessment of Latching as Control Strategy for Wave-Energy Point Absorbers

摘要

Wave-energy point absorbers can be described as linear, under-dampedrnoscillating systems excited by ocean waves. These devices are intendedrnto be installed offshore and operated in a variety of wave conditions,rnwith a view to producing energy from the oscillations they undergo.rnLatching control, a technique meant to improve the absorption ofrnenergy by point absorbers, has been the subject of many studies in thernwave-energy literature. The present paper outlines the original principlernof latching control and proceeds with a critical assessment of thisrncontrol strategy and of some of its variants, from both a theoretical andrna practical point of view.
