Servo Motor Position Control Test Bench with PID Tuning

Approx. component budget: Rs. 6,000 - 11,000

Objective

Tune a PID controller for position control and compare tuning methods under different loads and disturbances.

What you will build

A DC servo motor with an encoder, a motor driver, a microcontroller with a PID controller, a disturbance weight arm and a serial plotting interface.

Results you can expect

• Step response with different gains
• Overshoot and settling time
• Effect of load
• Comparison of Ziegler-Nichols and manual tuning

What you will learn

Closed-loop control, PID tuning and encoder feedback, the foundation of industrial motion control.

Tools and notes

Arduino/ESP32, encoder motor, motor driver, Python or Serial Plotter. Keep fingers clear of the rotating arm.

Resume points from this project

• Built and tested Servo Motor Position Control Test Bench with PID Tuning; objective: tune a PID controller for position control and compare tuning methods under different loads and disturbances.
• Measured and analysed step response with different gains and overshoot and settling time; 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.
