Demanded pitch sensor


The Pitch sensor can be added by clicking on the sensor icon of the Pitch part, as shown in the picture below:



The Demanded pitch sensor is not available for Fixed pitch.

The Pitch sensor provides the following fields:
FieldUnitDescription
Demanded collective pitch angledegreesthe pitch angle requested by the controller
Cumulative collective demanded pitch angledegreesthis output sums up the variation of all the pitch angle values reached during a simulation, in absolute value. For example if the pitch angle goes from 0 to 1, this output will be 1. If the pitch then goes to 2, this output will be to. If the pitch then goes back to 1, this output will be 3. 
Demanded collective pitch angle ratedegrees/sthe speed at which the demanded collective pitch angle is changed (i.e. the time derivative of the Demanded collective pitch angle output)
Set pointrpmwhen the pitch controller is active, the PID controller will adjust the pitch so that the generator rotational speed is close to the set point (only available for PID scheme)
RPM errorrpmthe difference bewteen the current generator rotational speed and the Set point (only available for PID scheme)
P termdegreesthe pitch correction due to the proportional term of the PID controller (only available for PID scheme)
I termdegreesthe pitch correction due to the integral term of the PID controller (only available for PID scheme)
D termdegreesthe pitch correction due to the derivative term of the PID controller (only available for PID scheme)
Gain scheduling factor-correction factor applied to correct the PID terms for the current pitch angle. See Jonkman et al. (2009k) for detailed info. (only available for PID scheme) 
DLL response timemstime elsapsed between Ashes calling for a value and the DLL returning the value (only available for Bladed DLL type)
