Quantification of the Prediction\ud Requirements in Reactive Control of Wave\ud Energy Converters

摘要

Optimal reactive control for maximum ocean wave power absorption from Wave\udEnergy Converters (WECs) consisting of oscillating systems, is based on the principle of tuning\udtheir oscillation so that it is in resonance with the excitation force produced by the incident\udwaves. Reactive control, however, is non-causal and cannot be implemented in real time. This\udpaper analyses the prediction requirements of one possible solution, where predictions of the\udexcitation force are utilised to resolve the non-causality. The study is focused on the analysis\udof the required forecasting horizon against the achievable prediction. Also, through the aid of\udnumerical simulations of a number of specific systems over several wave conditions, a link is\udfound between some fundamental properties of the system and the prediction requirements.
