Abstract
The present invention is a method for real-time determination of the forces exerted by incident waves on a mobile part of a wave energy system. Models are constructed of the radiation force exerted on the mobile part and of the drag force exerted on the mobile part and a non-linear model of the wave energy system dynamics. The invention uses only measurements of the float kinematics (position, velocity and possibly acceleration) and of the force applied by a converter machine, which measurements are normally available on a wave energy system since they are used for control and supervision thereof. Determination of the excitation force exerted by incident waves on the mobile part uses the models, the measurements and an unscented Kalman filter.
