Make feedback
feel real.
Change a gain. Disturb a system. Watch the machine and every signal respond together. Learn control by testing what you think will happen.
This trace is calculated from the same motor model used in the lab. Move the gain to see the response change.
From a guess to an explanation.
Build intuition, then go further.
DC MOTOR
Follow a speed target. Explore P, I and D, saturation, load torque and sensor noise.
Explore experimentCART-POLE
Keep an inverted pendulum upright. See why balance alone does not bring the cart home.
Explore experimentMASS–SPRING–DAMPER
Release a mass. Compare damping, energy and resonance before adding a controller.
Explore experimentTHERMAL CONTROL
Compare ON-OFF hysteresis and PI. Explore heating limits, integral windup and passive cooling.

The model is part of the lesson.
Every plot, metric and drawing comes from a documented browser simulation. Compare runs with identical conditions, replay any instant and inspect the equations behind the result.

A practical answer about experiments, saturation and when a model becomes useful.
