Options
ValueWhat it doesWhen to use it
tsr curve

A target tip-speed ratio driving a torque controller from a lookup curve; the user must specify a tip speed ratio curve.

fixed

For a fixed controller the user must specify an angular velocity and blade pitch angle.

schedule

Sets pitch and rotational speed by interpolating pitch_schedule and speed_schedule tables against the reference wind speed, and stops the rotor outside their range.

Not available from a validated deck, as the schema does not accept pitch_schedule or speed_schedule.
