Content of review 1, reviewed on July 28, 2020

There are too few and irrelevant experimental results. Put more results from simulations and from experiments.
All experimental results are for no-load regime. For this reason the results are not suggestive.
The references list is OK.
Compare the results thus obtained, with those from other control methods used in PMSM.

Improve the figures from experimental results. Different lines or symbols that are not related to the graphic representation appear on each figure facing outside the border.
Compare your results with other control methods.

Even if it is a difficult period for the research activity, you must continue and deepen this research, publishing other results in future works.
