NREL 5MW Control design - Power deviation

This forum if for discussing controls. Questions about how to implement controls in FAST are more appropriate to the CAE Tools forum.

Dear Jason,

Ok thank you, now I understand better.
And when you said "If you can prescribe the generator torque and pitch ramps...", you mean that the generator torque will not be zero below cut-in generator speed such as the control logic of Servodyn.f90 or zero above cut-out wind speed?

Best regards,
Etienne

Dear Etienne,

I would expect that the generator torque would be zero below cut-in or above cut-out wind speeds. But there is likely some ramp-down of torque when transitioning from operational to idling modes.
