WAVE ENERGY CONVERTERS

摘要

By approximating the motion of a wave energy converter (WEC) device and of the excitation forces acting on the device, each as a finite, truncated combination of basis functions, the equations of motion describing the device can be reformulated as a linear system and the problem of the constrained energy maximization can be reformulated as a non linear program expressed in terms of a cost function and a constraint. This can be solved in real time to arrive at a force profile for a PTO which, when implemented by the PTO, maximises the energy available from the PTO while staying within the physical constraints imposed by the device.
