This collaborative research project aims to establish methodologies for an integrated design paradigm for wave energy devices, by testing and validating a radically new control co-design approach to create a mutually-efficient power take off and wave capture structure, with active mechanical motion rectification, co-optimization, and advanced control, to significantly improve the efficiency, increase the power output, and decrease the peak-to-average power ratio. The project team is composed of experts in three countries on wave capture structure, power take-off, and control systems design who work closely together throughout the co-design process from early state of concept design, and component modelling, to system integration. The project partners include Queens University Belfast and Virginia Tech. The Maynooth University team will focus on control strategy. This project is funded by Science Foundation Ireland and the National Science Foundation (US).
