Reviewer 2 Report
This paper is to design a reduced-order extended state observer-based active vibration controller for a structural vibration control system with all disturbances, including model uncertainties, higher harmonics, and external excitations. A reduced order extended state observer 15 (RESO) based nonsingular terminal sliding mode vibration control (RESO-NTSMVC) method is 16 proposed for the vibration suppression of an all-clamped plate structure with inertial actuator. First, a second-order state space model of the thin plate with a inertial actuator is established by solving the dynamic partial differential equation and analyzing the physical model. Second, the total disturbances, i.e., model uncertainties, higher harmonics and external excitations, can be estimated and compensated by a RESO via a feedforward part. Third, a NTSMVC based on estimated value is designed to obtain the fast tracking rate and effective vibration suppression performance. In addition, the stability of the closed-loop system is proved by a Lyapunov stability criterion. Finally, a semi-physical experiment equipment is built based on MATLAB/Simulink real-time environment and the NI-PCIE6343 acquisition card to verify the strong anti-disturbance performance and effective vibration control performance of the designed method.
I think the subject matter is interesting. So, the following points can be very helpful if you want to accept the manuscript:
1- Innovation isn't enough.
2- Please list the initial motivations of the manuscript.
3- The literature review should ideally be presented in a distinct section, and any relevant works, especially those published between 2020 and 2022, should be included. An organized table that includes all relevant metrics is also recommended.
4- The section 2 of System Description should be written by more details and clearness.
5- The equations (7) are studied in many literature. What's the new and motivations?
6- Detailed information about the utilized computer programs and hardware must be given.
7- It's important to check the results against other current studies in the field.
8- The future works paragraph should be presented in more detail in the conclusion.
9- More analysis and numerical results should be added.
10- The future works paragraph should be presented in more detail in the conclusion.
