A page to observe the behavior of a fixed PID controller
when subjected to colored (low-frequency) and state-dependent disturbances,
using time responses only.
- No sliders
- No position animation
- No excessive explanation
Only these signals are shown:
y(t), setpoint(t), disturbance(t)
Live Demo
What this shows
- Why the PID appears to be tracking correctly
- Why low-frequency, state-dependent disturbances are effective
- Where phase and integral action break down
The conclusion is not in the code — the waveforms speak for themselves.
Controls
R: ResetSPACE: Inject disturbance (for observation)
Notes
This page is intentionally minimal.
If you need intuition, look elsewhere.
If you need truth, look at the time response.
