Quadcopter Flight Control

How does a drone hold still in the wind? Nested PID loops turn position error into tilt into thrust — tune the gains and click waypoints to fly.

A quadcopter holds position with nested control loops: an outer loop turns position error into a desired tilt and thrust, and an inner loop drives the attitude to that tilt. Tune the PID gains for a snappy, stable response — too little derivative and it oscillates, too much and it sluggishly drifts. Click to send a waypoint.

Governing equation

m \overset{z}{¨} = T - m g, T = m g + K_{p} e_{z} + K_{d} \overset{e}{˙}_{z}, K_{p} = 1.0, K_{d} = 1.4

Reading this result: Balanced gains (Kp=1, Kd=1.4) give a snappy, stable approach with minimal overshoot.

How it works

A quadcopter stabilizes with cascaded control: an outer position loop computes the tilt and thrust needed to reach a target, and an inner attitude loop drives the craft to that tilt. Tuning the PID gains trades responsiveness against stability, and wind gusts test the controller. Click anywhere to send a new waypoint.

Frequently asked questions

Is this quadcopter PID flight control tool really free?▾

Yes. Quadcopter Flight Control runs entirely in your browser using your device's own compute, so local use is free forever. You only pay Compute Tokens if you scale a job to the cloud.

Do I need to install anything?▾

No. Everything runs client-side in a modern browser — no downloads, no license, no account required to start.

Can I save or share my simulation?▾

Create a free account to save projects, and use a shareable embed or minted DOI to publish a live, interactive version anywhere.

How accurate are the results?▾

The solver uses established numerical methods, but results are for research and educational purposes and should be validated against experiment or professional review before you rely on them.
