EXPERIMENT 03 · DC MOTOR

What does P change?

Will a higher P gain reach the target faster without a cost?

Try it in the current lab

Pin the baseline, then increase P by 50%.

Pin the baseline, raise P, then compare rise time, overshoot and requested voltage.

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

More proportional action reacts harder to the present error. Saturation and overshoot can appear before the target settles.

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