1. What are the contributions in this paper?

This paper describes a complement to the autotuning ATV method.

2. What are the future works in this paper?

4. HB identification for system 1 and n=2 Another topic in a pre-tuning task is the possibility of using this method as pre-tune values or use the averaged parameters of alternative tuning methods.. In any case, the possibility of comparing the results of several methods increases the reliability of the autotuning test.. As a general criterion, it can be assumed that the appropriate excitation frequency will be the maximum value for which the controlled system responds properly under a desired phase margin.
