Multi-Valve Coordinated Disturbance Rejection Control for an Intake Pressure System Using External Penalty Functions

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This paper proposed a multi‑valve coordinated disturbance rejection control for an intake pressure system. However, the following comments should be addressed:

• How to design ADRC for the intake pressure system? This revision lacks this part.
• The control difficulties of the intake pressure system, such as nonlinearity and decoupling, should be added.
• How to obtain the parameters of the designed ADRC.
• The robustness analysis of the designed ADRC should be analyzed.
• The language is suggested to revise carefully.
• High resolution figures of Fig7-Fig 10 are replaced in next revision.

Reviewer 2 Report

Comments and Suggestions for Authors

The manuscript is generally well-structured and clearly presented. Theoretical analysis as well as some HIL test results are provided. However, the following issues remain to be addressed before the manuscript can be considered for publication..

 

• More details should be provided about the real-time simulator used in the HIL test platform..

 

• To ensure the fairness of the comparison, the authors should clearly describe the methodology used for selecting the parameters of the tested PID controllers.

Reviewer 3 Report

Comments and Suggestions for Authors

• I would recommend the authors to describe the experiments and the results achieved in more detail.
• Was PID regulation used, as mentioned in the text of the article? In Fig. 5 you indicate that it is a PD controller. How did you determine the parameters of the regulator?
• The article lacks a detailed analysis and discussion of the results.
