The purpose of PIDlab is to introduce free virtual laboratories for PID tuning, design and application. With these interactive tools, you can do "PID tuning in one minute". You can learn a lot about PID control and autotuning, predictive control and advanced PID control structures and schemes. The applets can be used for all educational, RTD and commercial purposes.

All presented algorithms are included in REXYGEN real-time control software. There are various hardware platforms supported for real-time control.

Visit REX Controls web page or contact us if you are interested in implementation of presented algorithms into your device or system.

Virtual laboratories are available online at
