The function of the fuzzy logic is to set the PID parameters internally to achieve a
flexible and adaptive output manipulation MV for different processes. For example:
The temperature difference is large and the change is fast, then ∆MV is large.
The temperature difference is large and the change is slow, then ∆MV is small.
The combination of PID + Fuzzy Control has proven to be an efficient method for
optimising the control behaviour, please refer to the following diagram for a compa-
rison of the control curves.
