EcoStruxure™ Control Expert - Fuzzy Control Library
Overview
Process Control Engineering with ready to use function blocks of Fuzzy Control Library
Fuzzy Logic controllers contain rules engines which process generalized (fuzzy) rules to produce a crisp output.
The output is driven by the rules and performance is managed by the accuracy of the rules.
The rules need to be maintained to deliver optimal control.
The main idea of Fuzzy Logic is the dealing with ambiguous quantities, the
elements of which only gradually belong to a set. Instead of just ’membership’ and ’non membership’, intermediate stages are also permitted. With the help of Fuzzy Logic, ambiguities of different kinds can thus be mathematically described and handled.
This theory finds its successful application in control engineering as Fuzzy Control.

Benefits
Fuzzy Control in EngineeringIn control engineering, one or more control variables are produced depending on one or more input variables.
The input variables are fuzzified
The linguistic variables produced are associated with the corresponding
operators in accordance with specific rules. Result of the processing of the rules (inference): a ’fuzzy’ output variable, that is to say a variable which is described with its membership degrees through attributes.
Defuzzification of the output variables into a unambiguous number with which an
action can then be associated in the control process.
