The Effect of Dead-Time and Damping Ratio on the Relative Performance of MPC and PID on Second Order Systems

Round 1

Reviewer 1 Report

The manuscript is nicely written and covers different comparative assessments of standard PID and MPC schemes. I have the following minor suggestion for the authors.

1. The authors should discuss similar comparative literature and should mention how the presented work is different from that of the literature.

2. Stability and sensitivity need to be studied for both controllers.

Reviewer 2 Report

The work is well thought out, but less well presented in my opinion.

Introduction is really complicated and bad understanding for the first read.

You present typical second order system in introduction. Please refer on (4) directly and try to described real system examples. It is important for Kp and tau settings relevance in chapter 3.

Equations (5-6) includes formal mistakes or I do not understand them.

In line 153 - KID3 should be labeled instead of K3?

Have you considered a graphical representation of the results? A large number of very similar tables is confusing.

Please, Be careful when sharing relationships act. - For example line 451 - 452.

In conclusion, there is important to give an objective assessment of how MPC is better and from which systems... Not only better, please. Try to represent it in small table or by graphic.

Thank you for your work. Try to improve conclusion especially, please.
