What is an Autotuner
An autotuner is something capable of computing the parameters of a regulator connected to a plant (i.e. tuning that regulator) automatically and, possibly, without any user interaction apart from initiating the operation.
The best way to understand autotuners is to analyze how a PID regulator may be manually tuned by a human. The basic steps of a tuning process may be summarized as follows
Formalizing these steps establishes a tuning method. An autotuner is then an implementation of a tuning method capable of running automatically.
The "description" of the process may be obtained in two ways:
Tuning rules can be constructed in several ways:
