Optimal control techniques can oversee the power take off (PTO) operation of wave energy conversion systems to ensure that the overall power output is maximized, but optimization in real-time poses difficulties given the wave variability and the underlying constraints of the system. This study examines several different model predictive control (MPC) approaches that utilize a model of the hydrodynamics of the wave energy converter as well as the dynamics of a hydraulic PTO system. The impact of accounting for various dynamics in the optimization and the role of constraints on the wave energy converter performance is explored for irregular wave conditions.
