Modeling and Analysis of an Inertia Wave Energy Converter and Its Optimal Design

A novel structural design of a wave energy converter (WEC) is proposed, utilizing gyroscope as the main component for absorption. vacuum-sealed, high-speed flywheel implemented within to convert and reduce loss from air resistance. dynamic model that considers response floater, gyroscope, power take-off (PTO) system with multi-degree-of-freedom (DoF) excitations created. The primary parameters such speed, damping, stiffness WEC affect PTO on absorption are analyzed through numerical simulations. simulation results demonstrate changes these can significantly impact energy-absorption peak value. Furthermore, an improved multi-objective evolutionary algorithm based decomposition (MOEA/D) applied optimize key parameters, conversion gyro precession system, using hybrid constraint handling strategy enhanced diversity HV value evaluation criterion. optimal solution selected Pareto set technique order preference by similarity ideal (TOPSIS) method entropy weighting so technical guidance be provided control system.
