Application of Linear Model Predictive Control to the ISWEC

Abstract

Wave energy is one of the promising offshore renewable energies. Nowadays many different kind of prototypes are being studied, designed and developed. ISWEC is a gyroscopic effect based device, with a sealed hull and slack mooring. The analysis of the system dynamic and its optimized control are cur-rently under research. In this paper, an online control technique is proposed, using linear MPC algorithm and implementing an observer over an augmented model, which can model and predict the incoming wave in a novel manner. Some comparisons with an optimized spring-damper existent control technique are shown. At the end, an evaluation of controller’s hardware feasibility is also presented
