AB  - We propose a novel formulation for declutching control of wave energy converters with the power takeoff time as the only decision variable. The optimal control problem is modeled as a single-variable optimization problem, thereby making real-time implementation a possibility. We present a derivate-free optimization algorithm that exploits the quantization of the decision variable in order to reduce the number of function evaluations needed to compute a solution. We propose two receding horizon closed-loop strategies: the first one uses past wave information and can increase the energy generation by 42% compared to the uncontrolled case, while the second formulation uses predictions of future waves and results in a further 40% increase in energy generation. For irregular waves with peak periods longer than 6 s, one can generate at least four times more energy when co-designing the physical system and controller, compared to a controlled system that was optimized without a controller in the feedback loop.
