PID Controller Tuner

PID controllers run everything from thermostats to drones. Drag the three gains and watch the system settle — or ring and overshoot.

Presets

A PID controller drives a system to a target using three terms: proportional reacts to the current error, integral erases steady offset, and derivative damps overshoot. Tuning them trades speed against stability. Educational tool.

Governing equation

Reading this result: The response never settles within ±2% — the loop is oscillatory or unstable, so back off Kp and Ki and add derivative damping.

How it works

A PID controller sums three responses to error: proportional (present), integral (past), and derivative (future trend). Raising Kp speeds response but risks overshoot, Ki removes steady-state error, and Kd adds damping. Tuning balances speed against stability. Educational tool.

Frequently asked questions

Is this pid tuning simulator tool really free?▾
Yes. PID Controller Tuner 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.
