Note Precautions on the use
Self-tuning is affected by the present control results, as it is a function to correct the PID constant using
responses from the normal control.
Under the following environments, precise compensation may not be possible.
(1) Control system with large disturbances (when hunting-like operation appears due to disturbances)
(2) Control system with much time required for providing control outputs
Under the following cases, use auto-tuning.
(1) Where overshoot suppression is focused
(2) Where target follow-up characteristics are focused
(3) Where disturbance response is focused
(4) Control system with fast response (soldering gun, etc.)
(5) Control system with much dead time (constant-temperature bath, etc.)
