Abstract :
In this work, we consider the optimization problem of ocean wave energy absorption in oscillating-body systems. A solution based on discrete-time extremum seeking control is proposed to improve the mean extracted power by a power take-off (PTO) mechanism under different wave climates. Two different PTO mechanisms are considered: a linear and a non-linear one. Simulation results, obtained from an oscillating-body system subject to incident regular and irregular waves, are presented to show the feasibility of the proposed scheme.
