Hierarchical Fuzzy Logic System

FuzzyDesigner includes library of components, which allows a user to design a complex hierarchical fuzzy systems. The following components are included:

  • Input Port - stores fuzzy or crisp input values of the fuzzy system, crisp value can be preprocesses by the user defined linear digital filter
  • Input Linguistic Variable - stores linguistic terms and is used for classification of the actual component input (crisp or fuzzy value) into reference fuzzy sets
  • Rule Block - stores rules, performs fuzzy logic inference based on fuzzy rules and computes degrees of fulfillment of consequent variables from degrees of fulfillment of premise variables
  • Intermediate Linguistic Variable - is a bridge for logical chaining of rule blocks
  • Output Linguistic Variable - stores parameters of functional terms and computes an output value from degrees of fulfillment of all terms
  • Output Takagi-Sugeno Variable - stores parameters of functional (linear or constant) terms and computes an output value from degrees of fulfillment of all terms
  • PID controller - allows intelligent supervision of the conventional PID controller
  • Output Port - stores fuzzy or crisp output values of the fuzzy system
