Fuzzy Logic Designer

Design and test fuzzy inference systems

Description

The Fuzzy Logic Designer app lets you design and test fuzzy inference systems for modeling complex system behaviors.

Using this app, you can:

  • Design Mamdani and Sugeno fuzzy inference systems.

  • Add or remove input and output variables.

  • Specify input and output membership functions.

  • Define fuzzy if-then rules.

  • Select fuzzy inference functions for:

    • And operations

    • Or operations

    • Implication

    • Aggregation

    • Defuzzification

  • Adjust input values and view associated fuzzy inference diagrams.

  • View output surface maps for fuzzy inference systems.

  • Export fuzzy inference systems to the MATLAB® workspace.

Open the Fuzzy Logic Designer App

  • MATLAB Toolstrip: On the Apps tab, under Control System Design and Analysis, click the app icon.

  • MATLAB command prompt: Enter fuzzyLogicDesigner.

Programmatic Use

fuzzyLogicDesigner opens the Fuzzy Logic Designer app.

fuzzyLogicDesigner(fuzzySys) opens the app and loads the fuzzy inference system fuzzySys. fuzzySys can be any fuzzy inference system structure in the MATLAB workspace.

fuzzyLogicDesigner(fileName) opens the app and loads a fuzzy inference system from a file. fileName is the name of a .fis file on the MATLAB path.

To save a fuzzy inference system to a .fis file:

Introduced in R2014b
