Zero Average Dynamic Controller for Speed Control of DC Motor

Round 1

Reviewer 1 Report

1. Very interesting research on zero average dynamics to control fourth-order nonlinear model of DC motors in a well prepared manuscript that needs some mild revisions.
2. Abstract is okay but is not likely to entice the readership to continue reading the rest of the manuscript.
   • Use of acronyms/abbreviations in an abstract is unlikely to attract readers not already aware of the zero average dynamics or DC motors.
   • Results are only presented in weak, qualitative fashion. Highest quality expression of main conclusions or interpretations is quantitative results discussed in the broadest context possible, e.g., percent performance improvement compared to a declared benchmark. “…showed the good performance…” is very weakly stated results compared to “…xxx percent performance improvement over conventional methods was achieved….”. Such ubiquitously understandable figures of merit are present in the manuscript, but not presented in the final sentence of the abstract nor in the conclusions.
3. Introduction is decently done with some omitted very recent literature amidst substantial citation (over half) from merely two groups of researchers (including self-citations), and some mild abuse of multi-citation without elaboration.
   • Especially due to its effectiveness for high order, coupled nonlinear models, the effective alternatives omitted include deterministic artificial intelligence of DC motors and predictive control of mechanics.
   • Please elaborate a reason for the reader to investigate each of the triple cited references [8-11].
   • Please elaborate a reason for the reader to investigate each of the triple cited references [24-26].
4. Equations are scientifically sound and well presented, enhancing the manuscript quality.
5. Figures are decently done with some mandatory improvements in general quality (blurriness) to ensure the readership has access to the content.
   • Internal font size is well presented to ensure legibility by the readership. Figure 5 has some illegibly small internal fonts.
   • Line styles and sizes are used effectively in figures rendering the disparate data easily distinguishable when the manuscript is read in printed hardcopy (particularly in black and white).
6. Tables are decently done aiding repeatability, and quantitative results listed afterwards are strongly asserted.
7. Please add such broadly stated figures of merit to the abstract (in a single sentence) and conclusions.

Reviewer 2 Report

Although the authors have done a good work in representing the paper, I don't see the contribution( the novelty of the paper). DC controllers have been proposed and used for a couple of decades and the literature is enriched with optimization approaches. 

The abstract has not highlighted any additional optimization, it is just an application of knowledge ( that has already been applied previously). 

Please Highlight the novelty of the paper (how is your work is different from others , how is it  better (using performance evaluation criteria).

Reviewer 3 Report

The title of the revised article is “Zero Average Dynamic Controller for Speed Control of DC Motor”. The authors present the use of the buck converter with zero average dynamics to control the speed of a permanent magnet direct current DC motor.

Reviewer 2 Report

The authors have managed to provide a detailed explanation of the report and have significantly enhanced their paper. Therefore, I have no further comments. Good Luck.

Thanks
