(5) PID2 control (Pid2)
This type of control reduces overshoot during control for processes that turn the control target off and then on again.
The algorithm used prevents over-integration 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.
