Fuzzy Logic in Simulink

Simulate systems in Simulink^®

Fuzzy Logic Toolbox™ software provides blocks for simulating your fuzzy inference system in Simulink. For more information, see Simulate Fuzzy Inference Systems in Simulink.

Blocks

Fuzzy Logic Controller	Evaluate fuzzy inference system
Fuzzy Logic Controller with Ruleviewer	Evaluate fuzzy inference system and view rules
FIS Tree	Evaluate fuzzy inference system tree (Since R2024a)

Simulate Fuzzy Inference Systems in Simulink
You can implement your fuzzy inference system in Simulink using Fuzzy Logic Controller and FIS Tree blocks.
Water Level Control in a Tank
Implement a water level controller using the Fuzzy Logic Controller block in Simulink.
Temperature Control in a Shower
Implement a water temperature controller using the Fuzzy Logic Controller block in Simulink.
Implement Fuzzy PID Controller in Simulink Using Lookup Table
Implement a fuzzy PID controller using a lookup table, and compare the controller performance with a traditional PID controller.
