Step 1:
First, set the
K
i
and the
K
d
to 0. Next, set the
KP
to 5, 10, 20 and 40 successively, and
record the target values and the process values. The results are shown in the diagram
below.

Step 2:
When the
KP
is 40, there is overreaction. Thus, the
KP
is not chosen. When the
KP
is
20, the reaction curve of the
PV
is close to the
SV
, and there is no overreaction.
However, due to the fast start-up, the transient output value (MV) is very big. The
KP
is not chosen, either. When the
KP
is 10, the reaction curve of the
PV
approaches the
SV
smoothly. Therefore, the
KP
is chosen. When the
KP
is 5, the reaction is too slow.
Thus, the
KP
is not chosen.
Step 3:
After the
KP
is set to 10, increase the
KI
. For example, the
KI
is set to 1, 2, 4, and 8
successively. The
KI
should not be larger than the
KP
. Then, increase the
KD
. For
example, the
KD
is set to 0.01, 0.05, 0.1, and 0.2 successively. The
KD
should not be
larger than ten percent of the
KP
. Finally, the relation between the
PV
and the
SV
is
presented in the following diagram.

Note:
The example is only for reference. Users have to tune the parameters properly according to the practical
condition of the control system
Programming Example
Using the automatic tuning function to control the temperature
Purpose: Using the automatic tuning function to calcaulte the most appropriate parameters
for the PID temperature control
Explanation:
Due to the fact that users may not be familiar with the characteristics of the temperature environment
