PID Simulator

A drone is constantly correcting itself. PID is the maths that decides how. Drag P, I and D, hit a preset, then press wind push and watch how each tune copes - both as a live drone view and as a step-response scope.

The faded drone is where your stick is pointing it. The solid drone is where it actually is. The gap between them is the error the tune has to close.

The same tilt, drawn over time. Up is more tilt, left to right is time passing. A good tune reaches the dashed target line fast and sits on it.

What the three terms are doing right now

Snap Pdrives toward target

Hold Ifights wind and sag

Brake Ddamps the swing

Overshoot

Holds target

yes

Motor heat

Locked in. Reaches the target fast, barely overshoots, holds against the wind and keeps the motors cool. This is the window you want.

Snap Ptoo high = bouncy45

Hold Itoo low = drifts80

Brake Dtoo high = hot motors30

This is a teaching model, not a Betaflight tune. The slider numbers show how each term behaves, not values to copy to a quad. Real acro tuning acts on rotation rate - the behaviour of each term is the same.
