SELECT PID CONTROL
The initial value of this "Control Parameter" is set i.e.
Proportional Band(P) = 3.0, Integral time(I) = 0 and
Differential Time(D)=0. Though the control can be done
by this initial setting, but please do Auto-Tuning for
getting better result in control. At the time of Auto
Tuning, set the unit to the condition of actual control by
connecting heater and sensors.
SELECT PID + FUZZY CONTROL
The parameter of this PID + Fuzzy Control is set at Initial
setting Value beforehand.
Should do Auto-Tuning.
At the time of Auto-Tuning, please set the unit to the
condition of actual control by connecting heater and
sensors.
