Control Playground

See why systems settle or swing.

Tune a PID controller, watch a mass–spring–damper move, and build intuition for overshoot, delay, noise, and saturation on your iPhone or iPad.

Offline experiment lab

Learn by changing one thing.

Control Playground keeps the first experience transparent: one model, five short experiments, live charts, and assumptions you can inspect.

Tune the loop

Move the setpoint and PID gains and see the response update immediately.

See failure modes

Turn on noise, delay, and actuator saturation to understand why control gets harder.
