Comments on “Distributed Synthesis of Local Controllers for Networked Systems With Arbitrary Interconnection Topologies”

In the article entitled “Distributed synthesis of local controllers for networked systems with arbitrary interconnection topologies” published in the IEEE Transactions on Automatic Control, vol. 66, pp. 683–698, 2021, there were some missing terms in Lemma 1 and the definition of the messenger matrices. Here, we include these terms and suitably modify the corresponding proofs. Note that all the main claims of the original article, including distributed analysis, distributed synthesis, and compositionality hold with the modified results.
