Toward More Realistic Social Distancing Policies via Advanced Feedback Control
Round 1
Reviewer 1 Report
Though R (double dot is the second derivative of R), it is important to at least mention this under equation 2 "where R double dot is the second derivative of R"
Author Response
Footnote 4 has been added in order to answer this legitimate query.
Reviewer 2 Report
This paper proposes an advanced feedbacck control for mitigating the COVID-19 pandemic. The control is based on the combination of flatness-based and model-free controls of the classic SIR model. The idea is interesting. However, there are some problems with the paper:
1. The captions of Figures 7-16 are incorrect. Only 5 scenarios are considered, but captions of Figure 13-16 are for senario 6.
2. What do the solid black and dash blue lines in the Figures mean? There are four line in each figure but only three labelled.
3. What does the transmission rate $\beta$ mean? How is it implemented in practice?
4. How are the parameters of iP(12) chosen? Some explanation should be given.
Author Response
Points 1 & 2 have been answered by suitable modifications of figures captations.
Point 3 is most legitimate although the transmission rate is the control variable in most control-oriented papers. This fact is made clear in the Introduction. The difficult of the implementation has been underlined at the end of the conclusion by mentioning the closure of nightclubs.
A few words have been added after Eq. (12) in order to answer Pont 4.
