A port-Hamiltonian Approach to Cummins’ Equation for Floater Arrays with Linear Power-Take Off Systems

Frequency-domain hydrodynamic modelling of dense and sparse arrays of wave energy converters

“…Particularly, the linear PTO in the present model is significantly different from the MP 2 PTO system in the OG-WEC concept. The recently proposed non-linear frequency domain model [23] or our time-domain port-Hamiltonian model [24] seems to be a promising approach to account for such nonlinearity and will be the focus of further work. The studied FB configurations employ several simplifications and assumptions, namely: constant mass of the floaters, constant stiffness of the spring joints, and uniform damping coefficients of the PTOs.…”

Practical Stabilization of Systems With Countable Set of Actions

“…Further method was proposed in [35] where passivity property of the radiation force is addressed. In addition, an explicit approximation to the radiation kernel is recently proposed in [36] where the formula is designed to approximate sinusoidal function with dissipating amplitude. The latter will be explained further as a part of this thesis.…”
