▶ Example according to PID control type
D.DV Control Description
▶ Output(MV) Change Rate is small in D.DV
control. It has small overshoot, and time
to reach TSP is delayed a little bit.
▶ It is proper to apply for equipment which
is sensitive to the change rate of
Output(MV).
D.PV Control Description
▶ Output(MV) Change Rate is big in D.PV
control. It has more overshoot and time to
reach TSP is quicker than D.DV Control.
▶ It is proper to apply for equipment which
responds late according to change rate of
Output(MV).
