Simulink. This example discusses the control system for a 1.5 MW wind turbine. This example models the rotor dynamics as a simple first-order system, which neglects the flexible modes in the drivetrain, blades, and tower. The focus is on the design and validation of a gain-scheduled controller for the blade pitch in high-wind regime.

Wind may be a free and unlimited fuel, but no matter how large or efficient a turbine is there's a mathematical limit to how much wind it can convert into electricity. German physicist Albert Betz calculated that since some wind must remain to keep the blades spinning, a turbine can only ever capture 59.3% of the wind’s energy.
