8. Auto-tuning of this controller
In order to set each value of P, I, D and ARW automatically, the auto-tuning process should be made
to fluctuate to obtain an optimal value. One of 3 types of fluctuation below is automatically selected.
For DC input, the AT process will fluctuate around the SV for conditions of (A), (B) and (C) below.
Sometimes the auto-tuning process will not fluctuate if auto-tuning is performed at or near room
temperature. Therefore auto-tuning might not finish normally.
(A) In the case of a large difference between the SV and PV (process variable) as the temperature is rising
When AT bias is set to 20 , the AT process will fluctuate at the temperature 20 lower than the SV.
(1) Calculating PID constant
(2) PID constant calculated
(3) Controlled by the PID constant
set by auto-tuning.
(4) AT bias value
(B) When the control is stable
The AT process will fluctuate around the SV.
(1) Calculating PID constant
(2) PID constant calculated
(3) Controlled by the PID constant
set by auto-tuning.
(C) In the case of a large difference between the SV and PV (process variable) as the temperature is falling
When AT bias is set to 20 , the AT process will fluctuate at the temperature 20 higher than the SV.
