Comments on "Stability analysis of uncertain sampled-data systems with incremental delay using looped-functionals [Automatica 55 (2015) 274-278]"
In a recent paper (Seuret & Briat, 2015), a looped-functional along with Wirtinger's inequality has been introduced to derive robust stability conditions for asynchronous and polytopic uncertain sampled-data systems. We point out that there may exist typos and errors in the looped-functional, the main results (Theorem 3.1 and 3.3) and Example 2. (C) 2016 Elsevier Ltd. All rights reserved.
