known. This wind input can be used to be varying parameter of the gain
scheduled controllers to adapt quickly their dynamics to the present wind.
• To improve the individual pitch controllers. If the pitch actuator bandwidth
increases, the performance of individual pitch controller would be better
because the wind effect in the blade modes can be mitigated.
• To improve the gain scheduled controllers in the above rated zone including
new operational points in the family of linear models when the wind turbine do
not work in the operational points of the curve of power production (Fig. 5.1 ).
• To improve gain scheduled controllers for wind gust inputs including a new
parameter dependence with a faster response than the pitch angle signal, like
the generator speed error, to have a better generator speed regulation in
extreme wind cases.
