OffsetPC:
--------------------------------------------------------------------------
Offset Pitch Control Algorithm
This "control" algorithm maintains a constant pitch angle, which in
general is not equal to zero. The pitch angle offset can be specified
in the file.
--------------------------------------------------------------------------
Form:
PitchInc = OffsetPC( theta, alpha1, offset )
--------------------------------------------------------------------------
------
Inputs
------
theta (1,1) Rotor angle (rad) [NOT USED]
alpha1 (1,1) Zero-pitch angle of attack [NOT USED]
offset (1,1) Desired offset angle
-------
Outputs
-------
PitchInc (1,1) Pitch angle control increment (rad)
