Abstract

Autotuning, or automatic tuning, means that the controller is tuned automatically. Autotuning is normally applied to PID controllers, but the technique can also be used to initialize more advanced controllers. The main approaches to autotuning are based on step response analysis or frequency response analysis obtained using relay feedback. Autotuning has been well received in industry, and today most distributed control systems have some kind of autotuning technique.
