The purpose of PIDlab.com is to provide free virtual laboratories (Java applets) presenting advanced PID control problems. Web brings tools for interactive PID tuning based on known process model or experimental data, tools presenting advanced PID autotuners for process and machine control and tools for simulating complex PID control structures applicable in industrial practice. The simulators are being used worldwide for teaching, training, R&D and commercial purposes.
PIDlab is a part of REX web farm. Within this group, you can visit ContLab.eu which collects more virtual labs above the scope of PID control. If you want to use the presented algoritmhs at real plant or machine go to REX Controls website.
