Optimized controller parameters
With both autotuning methods, the parameters for PI or PID controller structure are optimized according
to the configured controller type and the configured "Control structure" parameter: proportional band Xp
(P component), derivative time Tv (D component), and reset time Tn (I component).
The cycle time Cy and the filter time constant dF are also optimized.
The configured control structure is not changed by the optimization if it is a PI or PID control structure.
In all other cases, it is optimized to PID control structure.
For 1st order control processes, the parameters required for the PI control structure are optimized, inde-
pendently of the "Control structure" configured parameter.
