Application 3:
Using auto-tuning for temperature control
Control purpose:
Calculating optimal parameter of PID instruction for temperature control
Control properties:
Users may not be familiar with a new temperature environment. In this case, selecting
auto-tuning (S
3
+4 = K3) for an initial adjustment is suggested. After initial tuning is completed,
the instruction will auto modify control mode to the mode exclusively for adjusted temperature
(S
3
+4 = K4). In this example, the control environment is a heating oven. See the example
program below.
