Abstract
A proportional/integral/derivative control system is provided for controlling the operating parameters of a feedback system according to the difference between a measured value from a component of the system and a target set point. The control system employs a linearization curve having a plateau portion near the target set point. As the measured value approaches the target set point, smaller corrective measures are employed to minimize overshooting and fluctuations. Also, a range is established about the set point wherein no corrective measures are performed.
