Control of a Point Absorber Using Reinforcement Learning [PDF]
IEEE Transactions on Sustainable Energy, 2016 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.
