Paper title: Robust Double Active Control System Design for Disturbance Suppression of a Two-Axis Gimbal System

 

This paper addresses a robust controller design with disturbance decoupling and rejection of a two-degree-of-freedom Inertially Stabilized Platform (ISP). The authors provide the problem descriptions, the dynamic model and the control algorithm. Finally, some results were illustrated to validate the proposed method. The reviewer can see that authors have done numerous works on the related area. The reviewer thinks that the paper needs a minor revision before it can be accepted as a regular paper.

However, the reviewer has to add some remarks.

1) It is suggested that the authors should supplement labels and units in Figure 9.

2) In section 5, some statements should be illustrated in section 4. That is, the results should be analyzed deeply in section4.

3) This paper focuses on the problem of disturbance suppression, so some experiments and the corresponding results should be added.

Reviewer 2 Report

The current paper proposes a robust controller design with disturbance decoupling and rejection of a two-degree-of-freedom Inertially Stabilized Platform (ISP). The algorithm is validated through simulation results.

 

Comments to authors:

- Probably a stability mechanism can be added in order to improve the papers quality

- Please add more details of how the theory from the previous sections is applied in section 4.

- Please detail more the steps of implementing the algorithms should be added. The theoretical part is ambiguous. The steps will be in the benefit of the readers, maybe they’ll help the readers to implement the proposed algorithm.

- In this paper the authors speak about optimization problems, why no optimization problem isn’t proposed? No quality indicator is presented.

- The state of the art it is very poor and it should be improved with more references based on representative data-driven control algorithms from state-of-the-art, maybe the author could add the following publications:

o Hybrid Data-Driven Fuzzy Active Disturbance Rejection Control for Tower Crane Systems, European Journal of Control, doi https://doi.org/10.1016/j.ejcon.2020.08.001, pp. 1-15, 2019.

o Multi-Agent-Based Data-Driven Distributed Adaptive Cooperative Control in Urban Traffic Signal Timing, Energies, vol. 12, no. 7, pp. 1–19, 2019.

- The authors could add a paragraph with the disadvantages of the proposed method. In the current version only the advantages are presented.
