PID Water Tank Controllerv1.6

Set a target

Use the setpoint slider to choose your desired water level (0–100%).

Create a disturbance

Adjust the inflow slider to simulate water entering the tank — this is the disturbance the controller must counteract.

Tune the PID gains

Use the Kp, Ki, and Kd sliders to adjust the controller. Watch the chart to see how each gain affects response.

Change the tank

Adjust tank capacity (100–1000L) and valve slew rate to see how physical constraints affect controllability.

Auto-tune

Press Auto-Tune to let the algorithm calculate gains based on your tank size and slew rate.
