PI P gain PID Proportional gain of PI block
PI I gain PID Integral gain of PI block
PI steady thr Threshold feed-forward survey. If Feed-fwd PID is less than PI steady thr the integral
regulation will be frozen, the proportional gain assumes the value set in P init gain PID.
When Feed-fwd PID overcomes the threshold, the integral regulation with the gain
set in I init gain PID will be enabled. The PI block will mantain the gains P init gain
PID and I init gain PID for the time preset through PI steady delay. Once this delay
is over, they will be brought automatically to PI P gain PID and PI I gain PID.
