Control Systems & PID
Build intuition for closed-loop control by watching it work (and fail). Six interactive lessons, one sandbox.
Level 1
Open Loop vs. Closed Loop
Why do we need feedback?
Level 2
Bang-Bang Control
The simplest feedback.
Level 3
The P Term
Output proportional to error.
Level 4
The I Term
Kill steady-state error against constant loads.
Level 5
The D Term
Damp overshoot without nerfing speed.
Level 6
Tuning Challenge
Second-order plant with all three K terms, fight against the disturbance!
Free-play
PID Sandbox
Configure plant, gains, and setpoint waveform freely. No rails.
