   Custom Pitch Control Algorithm

   This control algorithm implements an control pitch angle
   increment as a function of the rotor angle such that the effective
   angle of attack follows a certain profile set in the file.

--------------------------------------------------------------------------
   Form:
   PitchInc = CustomPC(theta,alpha1)
--------------------------------------------------------------------------
   ------
   Inputs
   ------
   
   theta            (1,1)     Rotor angle (rad)
   alpha1           (1,1)     Zero-pitch angle of attack (rad) [NOT USED]

   -------
   Outputs
   -------

   PitchInc        (1,1)      Pitch angle control increment (rad)
