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)
Fuzzy PID Controller	Fuzzy logic-based PID controller (Since R2024b)

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
Implement a fuzzy PID controller using a lookup table, and compare the controller performance with a traditional PID controller.
Fuzzy PID Control with Type-2 FIS
Create a type-2 fuzzy logic PID controller and compare its performance with a type-1 fuzzy PID controller and a conventional PID controller.

Use a fuzzy PID controller to regulate the temperature of a house, balancing the trade off between comfort and cost.

Use a fuzzy PI controller for speed control of a permanent magnet synchronous motor using field-oriented control (FOC) principles.
