Pid2 Control; Changing To Pid2 Control - FujiFilm PXG4 Operation Manuals

PID2 Control

This type of control reduces overshoot during control for
processes that turn the control target off and then on again.
The algorithm used prevents overintegration of the PID
calculations even while the control loop is still open.
PID2 control can only be used after auto-tuning has been
activated and a Pid set.
