DC Motor Speed Control with Simulink

A control-systems study modelling a DC motor plant, designing a PID controller and comparing simulated response with a laboratory rig.

Open-loop motor speed drifted under varying load, making the process unrepeatable.

Derived the plant transfer function, designed and tuned a PID loop in Simulink, then validated step response and disturbance rejection on hardware.

System identification, model building, controller tuning, simulation, hardware validation and documentation.

Stable closed-loop response with reduced overshoot and settling time compared with the untuned loop.
