Motor-PID-Controller-using-Arduino-Matlab

A simple motor PID setup using Arduino and Matlab

Hardware Requirements:

• Arduino Uno
• Motor Dual H-Bridge L298 Driver https://circuit.rocks/motor-dualh-bridge-l298-driver
• Metal DC Geared Motor w/ Encoder https://www.dfrobot.com/wiki/index.php/12V_DC_Motor_251rpm_w/Encoder_(SKU:_FIT0186)

Software Requirements:

• Matlab R2016a +
• Arduino IDE

How to use:

• Edit COMPORT of Matlab code (PIDController.m) and run the GUI

handles.s = serial('COM5');

• Input P, I, D, and target speed (in RPM) values

• Click Send

• Update P, I, D to get the best response.

NOTES:

• After clicking Send, the motor should start moving and System Response details should start to populate and update.

• To test if PID works, try stopping the Motor (be careful - use piece of cloth), it should fight back.

• Motor response depends on P, I, and D values.

To understand the PID algorith included in the Arduino code, I recommend watching this video: https://www.youtube.com/watch?v=sDd4VOpOnnA
