Reviewer 1 Report

Comments and Suggestions for Authors

The contribution is a review article of the solved issue of ADRC, which is supported by 155 references to the literature. The article is well prepared in its current form, but from the point of view of scientific contribution, it does not bring new results in the given field of research. In the article, it is necessary to correct mainly formal errors:
- The pictures are too small, of poor quality, especially the curves in fig. 10 are illegible.
- As it is not the latest research, I would expect more examples and results from practical applications of ADRC and about the results achieved in the review.
- In the discussion and in the conclusion of paper, missing a clearer comparison of the results, e.g. in the form of a table

Reviewer 2 Report

Comments and Suggestions for Authors

Comments:

 

a) Please fix the equation numbering; all are (1)???

b) Please explicitly define the following expressions:

c) In the first equation just below line 151, what is fhan?

d) In the second equation below line 152, the rhs should be a sustraction, right?

e) Please explain the meaning of $fe$ y $fe_{1}$ in 2nd and 3rd equations below line 155.

f) How $\betha_{xy}$ in line 156 are chose?

g) In line 153, how is r selected? Does there exist a relation with uncertainty frequency?

h) In line 147, some assumptions related to the uncertainty must be considered; for instance, $f$ and $\dot{f}$ should be bounded. It can be justified using the following arguments in:

Stability of active disturbance rejection control for uncertain systems: A Lyapunov perspective." International Journal of Robust and Nonlinear Control 27.18 (2017): 4541-4553.

"Algebraic active disturbance rejection to control a generalized uncertain second-order flat system." International Journal of Applied Mathematics and Computer Science 34.2 (2024).

i) Equations should be appropriately aligned!!!!

Comments and Suggestions for Authors

This manuscript presents the ADRC’s integration with advanced technologies, highlighting its role in improving control precision and system robustness in precision agriculture.

The paper is well structured however some issues are the following:

1. Highlights should be includen at the end of section 1 of the manuscript.

2. Figures 2-4, 8,9, 10, 11, quality must be highly improved.

4. All equations of section 2 are wrongly numbered. Please fix. In addition, the first and second equations are presented in coninuous time and the rest are presented in discrete time. Please homogenize them. Also, it is suggested to use stadard ADRC terminology suh as in: https://www.sciencedirect.com/book/9780128498682/active-disturbance-rejection-control-of-dynamic-systems.

5.  All the references might be structured in tabular form regrading some criteria, for example application or variants of ADRC control.

I hope the above observations will help authors to sharpen their conclussions.
