An Intelligent Nonlinear Control Method for the Multistage Electromechanical Servo System
Round 1
Reviewer 1 Report
The authors are kindly asked to consider the following comments:
Q1- the abbreviation of “PMSM” is not defined in Keywords
Q2- Before designing the control system, it is necessary to provide an appropriate analysis of dynamic behaviors, nonlinearity, stability conditions, non-minimal phase behaviors, and interactions between the system variables. Procedure of designing control system is unclear.
Q3- The authors should use the symbol ® or TM for the software employed, for example MATLAB® (The MathWorks, Inc., Natick, MA, USA).
Q4- Simulink is a simulation package for MATLAB and this should be indicated.
Q5- On page 4, line 129, the reference link is missing.
Q6- How was the employed model for designing the controller validated?
Q7- The robustness of the designed control system should be evaluated.
Q8 - Please remove the grayscale background in Figure 9
Q9- Fonts are very small in plots.
Q10- How was the EMA frequency range chosen? Please elaborate.
Q11- More explanations are required for experimental setup and its components including sensors, data acquisition and so on.

Reviewer 2 Report
The paper presents effect results of a study on the development of the non-linear drive control system. The work contains a clearly detailed mathematical description of the system. There are comments on the work.
- In the figure 2, you need to check the direction of the arrows ua, ub, uc. And also to indicate the parameters and directions of the arrows from the SVPWM block
- In general, the description of the circuit in Figure 2 and the mathematical description does not include all the parameters of the system. The presented system model does not include sufficient information about the calculation of the parameters u_alfa, u_betta, ua, ub, uc.
- Figure 8 is not informative, it is better to present it as a diagram, rather than pictures of parts of the system (images are too small to get an idea of ​​​​the structure of the system)
- It is not clear how the data in Figure 4 was obtained. What is the reason why torque reaches its maximum at the 4-th second. For informational content, it is better to compare diagram 4 with the angle of rotation of the platform.
