Control of a Point Absorber Using Reinforcement Learning

  title={Control of a Point Absorber Using Reinforcement Learning},

  journal={IEEE Transactions on Sustainable Energy},
This work presents the application of reinforcement learning for the optimal resistive control of a point absorber. The model-free Q-learning algorithm is selected in order to maximise energy absorption in each sea state. Step changes are made to the controller damping, observing the associated penalty, for excessive motions, or reward, i.e. gain in associated power. Due to the general periodicity of gravity waves, the absorbed power is averaged over a time horizon lasting several wave periods… CONTINUE READING
