FuzzyDesigner Component Library 47
If the component input link is connected to a single rule block, the
output degrees of fulfillment just copy inputs. If the component input
is connected to several rule blocks, the output degrees of fulfillment
of stored linguistic terms are computed as a maximum of the
corresponding input degrees of fulfillment.
Connections
The input logical link of the Intermediate Linguistic Variable can be
connected to a component providing a DOF value (as result of fuzzy
inference in a rule block), that is, the Rule Block component.
The output logical link of the Intermediate Linguistic Variable can be
connected to components expecting a DOF value (as result of
fuzzification or fuzzy inference in a rule block), such as the Rule
Block component.
Parameters
• Name of the component
• List of terms defined by their names
Rule Block The fuzzy system Rule Block component stores rules, performs fuzzy
logic inference based on fuzzy rules and computes degrees of
fulfillment of linguistic terms for consequent variables (output logical
links) from degrees of fulfillment of linguistic terms used in the rule
for premise variables (input logical links).
