Control Strategy of Dual-Disc Electromagnetic–EMB Composite Braking System Based on Hybrid Systems

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The paper is interesting to readers, especially considering the redundant safety and mass production of EMB structures. Overall, the authors proposed a structural design of composite braking and developed a simulation model and conducted some experiments for verifying the effects. Thus, some revisions should be done before accepting to publication. Some questions：

1） Figure 1 should be depicted more clearly for ease of understanding.

2)  In section 2.2, the mechanism of the control structure of the EMB should be explained more clearly.

3)  The braking mode shown in figure 5 is too simple, I suggest, the author should add more details.

4)  In section 5, the experiment is conducted, but nothing i can see in your manuscript, please clarify.

5) Some expressions should be improved for readers‘ understanding.

Reviewer 2 Report

Comments and Suggestions for Authors

Dear Authors,
The manuscript is related to developing a control strategy for a composite braking system based on the hybrid control theory. Simulation models were built in MATLAB/Simulink, and numerical simulations were carried out. The title is correct. The abstract is clear. The list of references is extensive and adequate. The introduction is sufficient.

1. A more detailed explanation of "Brake controller 1" to "Brake controller 7" (Fig.2) is needed. The number, types and parameters of the controllers are not clear.
2. In the individual control modes, you use fuzzy and/or PID algorithms (Table 1). Parameters of these units should be provided. The adjusting process should be presented. Inputs and outputs should be described.
3. Methods of control unit connections should be described. E.g., m5 mode: Fuzzy PID + Triple closed-loop PID - how do they cooperate?
4. You mention four working conditions several times. Are there conditions explicitly described in the text?
5. The contents of Fig.8 and Fig.9 should be described and explained more extensively.
6. You admit that the research includes modelling and simulations only. Could you assess the correctness and adequacy of the constructed model concerning the real, physical braking system?
7. Formatting: Fig.1 should be embedded in section 2, not in the introduction.
