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:
Field Unit Description
Demanded collective pitch angle degrees the pitch angle requested by the controller
Cumulative collective demanded pitch angle degrees this 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 rate degrees/s the speed at which the demanded collective pitch angle is changed (i.e. the time derivative of the Demanded collective pitch angle  output)
Set point rpm when 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 error rpm the difference bewteen the current generator rotational speed and the  Set point (only available for PID  scheme)
P term degrees the pitch correction due to the proportional term of the PID controller (only available for PID  scheme)
I term degrees the pitch correction due to the integral term of the PID controller (only available for PID  scheme)
D term degrees the 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. (2009o)  for detailed info. (only available for PID scheme) 
DLL response time ms time elsapsed between Ashes calling for a value and the DLL returning the value (only available for Bladed DLL type)
