Gyro-System for Guidance with Magnetically Suspended Gyroscope, Using Control Laws Based on Dynamic Inversion
Round 1
Reviewer 1 Report
Comments and Suggestions for Authors1.The introduction part of the article has shortcomings. First, it should be compared with existing methods in more detail, especially to clarify the limitations of SGMSCMG and DGMSCMG systems, and how the proposed DGMSGG solves these problems. Secondly, the problem statement should be more clear and provide more sufficient reasons for the choice of dynamic inversion and Lie derivative method. In addition, the article can discuss the challenges in the practical application background in more depth to highlight the practical significance of the proposed method.
2.Although Simulink / Matlab is used for detailed simulation, there is still a lack of experimental verification. It is recommended to introduce experimental verification in subsequent studies to improve the applicability and credibility of the model.
3.Although the structure of the article is clear, some chapters (such as the non-linear model derivation in section 3) are too dense, the formulas are stacked, and there is a lack of intuitive explanation of key steps, which affects readability.
4.The paper mentions adaptive neural network control approaches but does not quantitatively compare the proposed method with other nonlinear or adaptive techniques such as sliding mode control, backstepping, or model predictive control. It is recommended to increase the performance comparison with other advanced control strategies to further highlight the advantages and scope of application of the proposed method.
5.In this paper, the effects of modeling uncertainties or external disturbances on the performance of the AMB-rotor translation and rotation subsystems are not analyzed. It is recommended to introduce a robustness study to evaluate the stability of the control system.
6.In the summary part of the thesis, the author lists seven innovations, covering multiple research levels. Too many innovations may lead to content fragmentation, affecting the depth of each innovation and the integrity of the elaboration. It is suggested that the innovation points should be summarized into several core levels, combined with qualitative and quantitative analysis to enhance the systematicness and conciseness of research contributions.
7.There are many format problems in the paper, such as insufficient picture clarity and disordered unit symbols. Please check carefully

Reviewer 2 Report
Comments and Suggestions for AuthorsThe manuscript presents a well-structured and technically rigorous control system for a magnetically suspended gyroscopic platform, using dynamic inversion-based design principles. The theoretical modeling is comprehensive, and the use of Lie derivatives and relative degree analysis demonstrates a strong command of nonlinear control theory. The decomposition into translation and rotation subsystems is logical and clearly motivates the chosen control architecture.
However, the paper would benefit from improvements in presentation quality. Several sentences in the abstract and introduction are overly long or redundant, which affects readability. We recommend refining the English expression for clarity, possibly with the aid of a language editing service. In the results section, Figures 5 and 6 include too many overlapping plots, making it difficult for the reader to interpret the key performance indicators; separating the plots or enhancing labeling would improve accessibility.
While the simulation-based validation is thorough, adding a discussion on practical implementation challenges—such as sensor noise, actuator saturation, or real-time computation—would enhance the relevance of the study. Additionally, highlighting potential aerospace or missile system applications more explicitly would increase the reader’s appreciation of the contribution.
Overall, this is a strong and valuable contribution to the field of gyroscopic control systems, and we encourage the authors to address the above points to improve the paper’s clarity and impact.

Round 2
Reviewer 1 Report
Comments and Suggestions for Authors1. The conclusion is overly lengthy and should be condensed to clearly highlight the main contributions and insights without repeating technical details from the main text.
2. The manuscript contains numerous linguistic issues, including redundant wordings and improper phrasing that significantly affect clarity and should be carefully revised—for example, the phrase “are are the currents applied to the stator coils of the AMB-rotor.”
