Multiplicative interference variable
The multiplicative interference variable can influence the control variable of the setpoint
controller over the entire control range proportionately to the interference variable. This
corresponds to a proportionality factor of 0.00 = 0% and 1.00 = 100 %, including all inter‐
mediate values.
