Appendix C

Manually Setting PID Constants

68

Derivative Time (D Constant)

Derivative operation is used to quickly return the temperature to its original value by providing a large output value
even if there is radical external disturbance.

Do not set the derivative time to be too long, otherwise a large temperature output value will continue to be output
and the temperature will not be stabilized. At this time, hunting of the temperature, with a cycle shorter than hunting
caused by incorrect proportional band or integral time values, will result.

Adjustment

Adjust the value of the derivative time from the larger value (longer time) to a smaller value (shorter time) to find the
optimum derivative time.

If there is hunting of the temperature with a short cycle, the derivative time may be set too long and the temperature
control response may be too fast.

Long derivative time is set.

Fuzzy Constants

Fuzzy constants are normally adjusted automatically. If, however, the results of automatic adjustment are not sat-
isfactory, or the response to external disturbance needs further improvement, the fuzzy constants can be manually
adjusted. The following flowchart shows how to manually adjust fuzzy constants.

Adjust fuzzy scale 2 only when fuzzy strength and fuzzy scale 1 adjustments are unsatisfactory.
