João C.C. Henriques,R.P.F. Gomes,Luís M.C. Gato,António F.O. Falcão,E. Robles,Salvador Ceballos +5 more
TL;DR: In this article, a power take-off control of an OWC (oscillating-water-column) spar-buoy wave energy converter was investigated. And the experimental results allowed the dynamic behaviour of the PTO to be characterized and provided validation of the proposed control algorithms that ensure operation within safe limits.
