Resonance control strategy for a slider crank WEC power take-off system

This paper presents a novel slider crank power take-off system and wave tracking control methodology for efficiently converting the energy of open ocean waves into electrical energy. The Wave Energy Converter (WEC) and Power Take-off System (PTOS) are modeled and a non-parametric control strategy to maximize energy extraction under regular sinusoidal wave condition is introduced. Energy extraction results from simulation are compared with theoretical optimums, and a number of factors that influence energy extraction are discussed. The study shows that a suboptimal wave energy conversion technique can be achieved.
