Two-Tank Level Control using Fuzzy Logic

Approx. component budget: Rs. 5,000 - 9,000

Objective

Control a nonlinear process with an easy-to-tune rule-based controller and compare it with classical methods.

What you will build

Two connected tanks with a pump and level sensors, controlled by a fuzzy logic controller, compared with a simple on-off and a PID controller.

Results you can expect

• Level error and settling time for 3 controllers
• Response to a leak or outflow change
• And pump energy used

What you will learn

Fuzzy sets and rules, nonlinear processes and controller comparison.

Tools and notes

Small pump, ultrasonic or pressure sensor, Arduino/ESP32, MATLAB or a Python fuzzy library. Use water-safe wiring and an enclosure for electronics.

Resume points from this project

• Built and tested Two-Tank Level Control using Fuzzy Logic; objective: control a nonlinear process with an easy-to-tune rule-based controller and compare it with classical methods.
• Measured and analysed level error and settling time for 3 controllers and response to a leak or outflow change; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
