Harmonic Suppression in Permanent Magnet Synchronous Motor Currents Based on Quasi-Proportional-Resonant Sliding Mode Control

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

Please, find my comments below:

1. No explanation of the symbols GR1, GR2 in Figure 1.

2. Inconsistency of symbol description between Figure 4 and equation no. 22 (remark on the symbol Ls).

3. Not a neat addition of units after values, once with a space other times without a space (E.g. line 309).

4. There is a lack of justification where there is a NEWFOUND approach that the system's ability to suppress harmonics is increased in the way the authors propose.

5. Approximately half of the references point to individuals from the same group of authors.

6. Many editing errors that interfere with the interpretability of the equations and diagrams used.

In my opinion, the article does not contribute anything novel to the discipline. Moreover, it is carelessly prepared, so that the evidence of its scientific value cannot be clearly read.

The propose is adequate because there are problems in process with the operation of the power inverter and with the pwm, e.i. harmonics +/-6n. The question is, why the needed of suppression of the 5° and 7° Harmonic? (for example, the 5° Torque Harmonic is more dangerous that the 7°, etc.). What problem present the 5° Harmonic? What problem present the 7° Harmonic? it is not clear in the introduction as motivation of the work.

Fig. 4 is not needed

 

For the experimental verification, it is not mention the load profile, dynamic, static, without load?

 The analysis of the results is not only the wave form of the current and of the torque, the THD analysis is more important, the FFT or complet fourier diagrams of the voltage and of the current are more important, thus the figures from 9 to 14 are only complement of the figure 15
