A wind turbine control apparatus, method and non-transitory computer-readable medium are disclosed. The wind turbine control apparatus comprises a generator connected to a wind turbine with a drive train. The drive train comprises a rotor, a low speed shaft, a gear box, a high speed shaft, and a controller module. The controller module is configured to obtain a maximum power within a large range of varying wind velocities by operating the rotor at a neural network determined optimal angular speed for the current wind velocity.

A method of controlling a tractor/baler combination is disclosed including the steps of: (i) advancing a tractor/baler combination through a swath or windrow of a harvested crop material with a tractor PTO operating at a generally constant speed to power a drive of a baling chamber of the baler and the baler operating to pick up harvested crop material; (ii) during step (i) assessing the flowrate of the harvested crop material in the baler and the torque of the baling chamber drive (iii) comparing the assessed flowrate with an optimal flowrate and the torque of the baler chamber drive with an optimal baler chamber drive; and (iv) if the assessed flowrate differs from the optimal flowrate by more than a predetermined amount or the assessed torque of the baler chamber drive differs from the optimal torque by more than a predetermined amount, changing the speed of advancement of the tractor/baler combination, and hence changing the flowrate of biological matter in the baler and the torque of the baler chamber drive.

A hull behavior control system includes a memory and at least one controller coupled to the memory. The at least one controller is configured or programmed to control a propulsion force of the marine vessel using a propeller of the marine vessel, obtain a water surface shape around the marine vessel, estimate movement of a wave based on the water surface shape, and reduce the propulsion force by controlling the propeller when it is determined that an impact force equal to or greater than a threshold value will act on the hull after the hull travels over the wave whose movement has been estimated.
