Process Control
and PID Autotuners

The PID autotuner is a design tool that automatically determines the parameters of a PID controller based on the response of the controlled process to a suitable input test signal. The goal is to achieve the best possible control performance while meeting the specified secondary requirements for the control loop. Since manual tuning of a PID controller is very time-consuming and, in the case of slow processes, practically impossible, many PID controllers are poorly tuned (often even using default parameters without proper adjustment). Poorly tuned controller parameters lead not only to lower control quality but can also cause unpredictable feedback loop behaviour and significant economic losses. A high-quality PID autotuner is therefore extremely useful for setting up and maintaining control systems.
