EXPERIMENT 01 · DC MOTOR

Find the feedback loop

Where does the motor speed go after you change the target?

Try it in the current lab

Move the target, then replay the response.

Use the response plot and the live target, actual speed and error readouts on one replay clock.

The lab recalculates after a setting changes. Pin a run before changing one variable; the response and control-effort plots share the same replay time. PID experiments also show the P/I/D terms; estimator experiments show measured and estimated states.

What the system is doing

The controller measures the gap and changes voltage. The gap shrinks as the motor responds.

L\dot{i}=V-Ri-K_e\omega,\qquad J\dot{\omega}=K_t i-b\omega-\tau_{load}
