Reviewer 2 Report

An article in the subject of Actuators Journal of MDPI

The well-written paper presents the research of  I a novel collaborative control strategy for the 3-DoF parallel mechanism to achieve both synchronized and differential motion. The structure of the article is relevant to the presented context of the paper

I propose a minor review to improve some details in the article 

In review please consider my remarks are presented in a few comments below.

Comment 1

In  

Figure 6. Comparison between simulations and physical experiments. Demand signals for the three groups of experiments are square wave signals with frequencies of (a) 0.1 Hz, (b) 0.3 Hz, and (c) 0.5 Hz, respectively.

you present three graphs a) b) and c) 

Please add descriptions for a) and b) graphs

Comment 2

Conclusions are relevant to the article but if you use of bullet list it is possible to improve the readability of this part

Reviewer 3 Report

The designation mentioned about the name of the controllers maybe is not correct, the author use collaborative controller, in my opinion, it is only cooperative, especially because the different controllers cooperate (with information to the others controllers) and do not collaborate (if one doesn't work the others can't do the job).
