Model-Free Predictive Current Control of Synchronous Reluctance Motor Drives for Pump Applications

Round 1

Reviewer 1 Report

This paper presents a predictive current control strategy for synchronous reluctance motors which does not require evaluation of the machine parameters and therefore does not require a preliminary modeling step of the machine. It is not perfectly clear why the application is limited to water pumps. The existing literature is adequate and clearly presented to introduce the topic of the paper.

The mathematical background is clear enough. The theoretical analysis relating to the implementation of the cost function is analyzed under all aspects, even the most critical ones. the experimental results are valid also supported by comparative analyzes with competing techniques and confirm, albeit under certain conditions, the effectiveness of the proposed technique.

Reviewer 2 Report

Comments
This research paper investigates the development of a current control algorithm for reluctance synchronous motors that does not require an explicit model of the motor, and that self calibrates in the first moments of operation without the supervision of a human expert.
1. It is strongly recommended that the authors check English grammar and vocabulary. Professional English editing service might be a good choice.
2. I think the font of formulas should be unified. Some variables in the formula are not explained. Please check it carefully.
3. This paper mentioned “A different paradigm in comparison to conventional PI current control of SynR motors is represented by the predictive current control (PCC) [14]….. It is important to stress out that the label model free still relies on a model for controlling the motor currents…” There are various studies in the literature which rely on a model for controlling to increase the control system robustness. The other MPCC cancels the cost function in [R1], it selects the optimal voltage vector based on a current track circle instead of a cost function. ------[R1] An improved model predictive current control for PMSM drives based on current track circle. It should be discussed and added in the introduction and reference parts.
4. The feasible voltage vector should be demonstrated clearly in Fig 1.
5. Some parameters need to be completed, such as the maximum torque of the motor. The description of the experiment procedure should be more detailed.
6. The formatting of the article needs some modification.
7. The drawback of the paper should also be mentioned.
8. Please highlight your contribution properly. It is not properly mentioned in the introduction.
9. Simulation and experimental results are not clear. Please enlarge them.
