I experimented with a neural network to steer the kite for the first AWE system I developed. (Supervised learning). It did work, but didn’t really provide any benefits (in my case) beyond traditional path planning and actuator control.

We have considered using reinforcement learning to optimise the control strategy for our hybrid turbine, but so far we have opted towards a more conventional wind turbine control strategy. Even controlling a wind turbine with just two actuators can be a daunting task.
