Development of a Real-Time Latching Control Algorithm Based on Wave Force Prediction

Optimal wave energy control is noncausal as the command optimized based on incoming force. Therefore, implementation of requires forecasting future A real-time latching algorithm short-term force prediction developed in this study to tackle such noncausality. The forces are forecasted using a gray model. receding horizon strategy used optimize online, over interval. Based predicted forces, power extraction maximized by locking and releasing buoy alternately according command. Simulation results show that increased substantially with algorithm, even if predicted. Effects length error conversion examined. It found more harvested when long employed while decreases efficiency. extreme load takeoff system increases implemented although its travel distance hardly varied.
