Your need to so the below:
In Simulink,
Develop / get a DC motor Model
Develop a PID Controller for the DC Motor
Develop Fuzzy Controller for the DC Motor
Compare the results on speed control (may be position as well)
Then Develop this in Hardware with Arduino + DC motor
You will need an encoder for the measurement + some hardware to start and stop (e.g button) + a LCD screen for display etc.
Deploy the PID controller on the Arduino for DC motor control
Deploy the Fuzzy logic controller for DC motor Control
Compare their performances and evaluate, discuss, recommend, etc.
You will likely need to customise the Simulink DC motor to match the Real DC motor
