EXPERIMENT 05 · DC MOTOR

Damping and noise

Can D calm overshoot while the sensor signal is noisy?

Try it in the current lab

Toggle noise and vary D while P and I stay fixed.

Compare the D contribution, speed response and requested voltage with sensor noise on and off.

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

D reacts to measured change. Filtering limits how strongly sensor noise reaches the actuator.

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