Description
Compensated setpoint determined for the input
specified by parameter
input
source.
The determination of the compensated setpoint
is based on the curve specified by points (x1, y1),
(x2, y2) and the non-linearity of the curve
specified with parameters 40.71...40.76. The
compensated setpoint curve will be a mixture of
a straight line between the points and a squared
line between the points:
