heal.abstract	A model for the energy exchanges involved in OWC power-plants is proposed. The model is using data series generated by numerical codes developed on the basis of relative physical principles. The ocean wave field and the oscillating water column are modeled according to linear water wave theory as a waveguide excited at both ends. The thermodynamic process inside the chamber is modeled with a control-volume approach. Then by applying identification techniques for linear and nonlinear systems, the corresponding operator representations are obtained in the frequency domain. A closed-loop is finally constructed which may find use in analysis and synthesis of OWC systems. Copyright © 2006 by The International Society of Offshore and Polar Engineers.	en
