We reveal that the upper bound of the closed-loop cost function provided by their Lemma 4 is erroneous. Some critical issues associated with the system initial conditions assumed in their paper are highlighted. The closed-loop cost bound claimed by their Theorem 1 is found to be incorrect. The optimization problem formulated in their Theorem 2 for the selection of an optimal guaranteed cost controller is erroneous. Finally, the corrections over their results are made available.<\/jats:p>","DOI":"10.1177\/0142331217732829","type":"journal-article","created":{"date-parts":[[2017,10,25]],"date-time":"2017-10-25T16:33:45Z","timestamp":1508949225000},"page":"3846-3850","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Comments on \u2018An LMI approach to non-fragile robust optimal guaranteed cost control of uncertain 2-D discrete systems with both state and input delays\u2019"],"prefix":"10.1177","volume":"40","author":[{"given":"Neha","family":"Agarwal","sequence":"first","affiliation":[{"name":"Department of Electronics and Communication Engineering, Motilal Nehru National Institute of Technology Allahabad, Allahabad, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haranath","family":"Kar","sequence":"additional","affiliation":[{"name":"Department of Electronics and Communication Engineering, Motilal Nehru National Institute of Technology Allahabad, Allahabad, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,10,25]]},"reference":[{"key":"bibr1-0142331217732829","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2006.06.002"},{"key":"bibr2-0142331217732829","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2010.07.014"},{"key":"bibr3-0142331217732829","doi-asserted-by":"publisher","DOI":"10.1016\/j.nahs.2016.11.001"},{"key":"bibr4-0142331217732829","doi-asserted-by":"crossref","unstructured":"Tandon A, Dhawan A (2016) An LMI approach to non-fragile robust optimal guaranteed cost control of uncertain 2-D discrete systems with both state and input delays.
