FUZZY CONTROL
Fuzzy control eliminates overshoot using Fuzzy
Logic. Employing Fuzzy control and Auto-
tuning, the controller effectively control as
below.
When the controller starts control at the
position which has a big gap between SV
and PV.
When reducing warming up time
When the load is fluctuating extreamly
When changing a set point value frequently

Control output is set in high and low limit as
operating range.
Output limit is -5 ~ 105 % of output.

When A/D error or input disconnection occur in
auto mode, PID output is cut and than Pre-set
output is operated. (PO Output)
