Addendum to “Seeking a Unique View to Control of Simple Systems”

This article extends the spectrum of basic structures with disturbance reconstruction and compensation considered in the paper from IFAC ACE'19 symposium and discusses problems met in their application, interpretation, teaching and learning. The objective is to foster a comprehensive understanding of basic control problems wrapped around the simplest first order plant models, which may be useful in dealing with their generalization to more complex tasks. Also included are remarks to some of the results and comments in the IFAC pilot survey on the introductory control course content.
