Reviewer 2 Report
Comments and Suggestions for AuthorsYour work is very interesting, the mathematics are hard to read, but they support your ideas. I think more explanation for the example is needed to have clearer idea to propose a control law for nonlinear systems.
In the first step of the control design, the matrix Gamma is proposed. An interesting point is to know if this matrix must be proposed to guarantee the stability of any positive definite matrix can be used.
In (10) I suggest using bigger parenthesis for a better presentation. The same for (16).
In (14) the inf function seems to be the infimum. Is it right?
To propose the initial values for \hat{h}, \hat{theta}, etc in (18) will help the reader to implement your ideas, I think all these values are small.
I thank the proof of theorem 1, it is a large explanation but it is possible to see all the details because in another way, it could be difficult to understand how the result was obtained.
In the simulation it is possible to see the good results of your technique proposed, also the initial values for (18). In my opinion, more explanation to propose (74) will be useful to the readers to build a signal control for other systems. Finally, I suggest adding the following references:

Reviewer 3 Report
Comments and Suggestions for AuthorsThe paper titled "Event-triggered Adaptive Control for a Class of Nonlinear Systems with Dead-zone Input" proposes event-triggered adaptive control utilizing back-stepping scheme for a class of non-linear systems under unknown parameters, dead zones, and external disturbances. The manuscript proposes a dynamic threshold with external disturbances. The manuscript provides prove that the error of the dead-zone stays bounded under the afore mentioned conditions. It also establishes boundedness of all signals of the closed-loop system. Finally, results are demonstrated through a numerical example.
The manuscript is average. Theory is sound and mathematically supported. However, presentation is poor and needs major revision.
Language needs major improvement. I would suggest never to start a new sentence with symbol. Avoid usage of two\three word sentences.
* What is joint-uncertainties mentioned in the abstract. Abstract is very short and contains unnecessary information, such as the sg() function.
* Please explain "v" in equation (2).
* Line 66: please avoid starting new sentence with a symbol.
* Equation (33) in Theorem 1 looks incomplete. If this is meant to be \Sigma, I would suggest using different symbol, since summation symbol is used in many places. Using \Sigma together with summation symbols causes confusion.
* Inconsistency in notation/difficult to follow. Suggesting to include notations section.
* Please expand Remark 3. Why is the bound of the (sign(x) - sg(x))^2 term 1? Please elaborate.
* Figure 3 caption contains a typo.
* Simulation studies section needs to be expanded. Consider showing the bound you have presented in Theorem 1.
* Consider showing how the estimation of unknown parameters evolves with time in the simulation.
* Show that Equation (70) is satisfied.

Reviewer 4 Report
Comments and Suggestions for AuthorsDear Authors,
After careful review, I regret to inform you that your submission does not meet the criteria for publication in the electronics journal.
The paper lacks the necessary linguistic quality required for effective communication. A thorough language revision is strongly recommended to enhance clarity and coherence.
Furthermore, the manuscript lacks novelty, and the absence of a comparative analysis with existing techniques diminishes its contribution to the field. A comprehensive literature review and comparison are essential to demonstrate the significance of the research.
Sincerely,
Author Response

Reviewer 4 Report
Comments and Suggestions for AuthorsI would thank the authors for the corrections and improvements they provided in their revised research paper.
The paper was already well presented, so I don't feel like giving another major for the latest shortcomings.
