Fuzzy Logic Controller

Fuzzy inference system in Simulink software


The Fuzzy Logic Controller block implements a fuzzy inference system (FIS) in Simulink®. See Simulate Fuzzy Inference Systems in Simulink for a discussion of how to use this block.

Dialog Box

FIS name

Specify the FIS as one of the following:

  • Structure — Specify the name of the FIS structure variable. For example, fismat.

  • File — Specify the file name in quotes and include the file extension. For example, ‘tipper.fis'.


  • You can generate embeddable C code for the Fuzzy Logic Controller block using Simulink Coder™ software.
