Resonance Control Based on Hydrodynamic Analysis for Underwater Direct Drive Wave Energy Converter
Journal of Marine Science and Engineering, 2021 Wave energy has great prospect among many forms of marine renewable energy for its high density and storage. This paper proposes an underwater direct drive wave energy converter (UDDWEC), which is composed of a submerged point absorbing buoy and a linear-
