All reviews of published articles are made public. This includes manuscript files, peer review comments, author rebuttals and revised materials. Note: This was optional for articles submitted before 13 February 2023.
Peer reviewers are encouraged (but not required) to provide their names to the authors when submitting their peer review. If they agree to provide their name, then their personal profile page will reflect a public acknowledgment that they performed a review (even if the article is rejected). If the article is accepted, then reviewers who provided their name will be associated with the article itself.
Authors have addressed all the comments from the reviewers. Hence, this paper is recommended to be accepted in its current form.

Authors have addressed most of the comments from the reviewers satisfactory. However, there are still some concerns about lacking of the explanation of the operation of FlexRay protocol and also clarification of whether updating of feedback gain is not necessary required in every sampling time. Authors need to carefully address these comments.
The content of the paper basically meets the requirements of the revision suggestions.
The experimental method is reasonable and the data analysis is quite reasonable.

The author's of this manuscript have made revisions based on the reviewer's comments and improved the quality of the paper. However, the authors can further modify it to improve the quality of the paper by adding the working of FlexRay protocol. In addition, authors need to clarify, whether updating of feedback gain is not necessary required in every sampling time.
The revised paper and response letter address all my comments from the previous review round. The paper follows established scientific reporting conventions, with each section flowing logically from the introduction to the experimental results and conclusions.
1. Remark 1 on page 5 of the revised paper is extended which addresses my question about the the advantages of both event-triggering and time-triggering over a single case.
2. The concern of "Robustness of the system" is well explained and answered.
The findings are valid and well-supported by the data.
All the grammatical issues are resolved which enhances the reliability of the paper.
After the first round of review, a "Major Revision" is recommended for this paper. Authors should carefully review all the comments, in particular to clearly explain the proposed network protocol FlexRay and enhance the validation of the proposed method.

The layout of Figure 1 is unreasonable. It is recommended to modify it to increase readability.
The name of "Control Inpuut" in Figure 3 and Figure 5 is wrong, please correct it.
In the experimental simulation part of this article, only using two examples for verification is not enough to prove the effectiveness. It is recommended to use 3-5 simulation examples for verification.
FRY is usually used in vehicle communications. Can the RMPC problem proposed in this article be applied to actual cars? Can it be simulated using CANoe and other software, or tested in actual vehicles.
it meets the requirements.
Contents in the manuscript pertaining to control theory. Manuscript contains control aspect more than the network mentioned in the title.
Illustrated with some examples.
Notations used should be clearly defined before its use. Some of the variables are described after its use.
The paper manuscript is well structured, communicating the research topic and contributions. In the introduction part, the author provides a solid background, demonstrating the values of Model Predictive Control (MPC) and the challenges associated with polytopic uncertain systems. The literature is well-referenced.
The paper adheres to standard scientific reporting norms, with each section logically progressing from the introduction to the experimental results and conclusions. Figures and tables are pertinent and well-integrated.
The experimental design is well-suited to the research question, addressing the challenge of implementing RMPC in high-rate networks governed by the FlexRay protocol. The research question is clearly defined and significant, tackling the complexities of controlling systems with uncertain parameters in a networked environment.
The methodology is sufficiently detailed to enable replication, with rigorous presentation of the mathematical formulations and RMPC strategy development. However, the paper could be strengthened by offering more detailed explanations of the algorithms used, particularly the rationale behind the selection of specific mathematical models and protocols. F
In Line 70: for example, why is a hybrid of both event-triggering and time-triggering superior than a single case?
The findings are valid and well-supported by the data. The authors effectively demonstrate that the proposed RMPC strategy manages system uncertainties while maintaining stability and performance. The simulations are compelling, illustrating that the proposed method surpasses traditional approaches in managing high-rate network constraints.
Nonetheless, the paper would benefit from a deeper analysis of the proposed method's limitations.
For example, discussing the potential effects of network delays or packet loss on RMPC performance would provide a more comprehensive understanding of the system’s robustness.
Conclusions: The conclusions are well-grounded, summarizing the key findings and their implications for future research in networked control systems. The authors successfully argue that their proposed RMPC strategy offers a viable solution for managing uncertainties in polytopic systems over high-rate networks. However, the paper could be improved by discussing the practical implementation of the proposed strategy in real-world scenarios where network conditions may vary.
General Comments: This paper contributes to the field of robust control systems, particularly within the context of high-rate networked environments. The integration of the FlexRay protocol with RMPC is novel and addresses a clear gap in the literature. The manuscript is well-structured, with a logical flow and adequate detail to support the authors’ claims.
While the paper is well-structured, numerous basic grammatical errors may hinder the reader's ability to understand the content seamlessly. I have highlighted a few examples below, but there are far more such errors! The authors are strongly encouraged to use proofreading tools to address all grammatical issues before publication.
