In order to improve the conservation of the existing robust stability analysis method, this paper considers a class of linear systems with norm-bounded uncertainty and interval time-varying delay as the research object. Less conservative robust stability criterion is put forward based on augmented Lyapunov-Krasovskii (L-K) functional method and reciprocally convex combination. Firstly, the delay interval is partitioned into multiple equidistant subintervals, and a new Lyapunov-Krasovskii functional comprising quadruple-integral term is introduced for each subinterval. Secondly, a novel delay-dependent stability criterion in terms of linear matrix inequalities (LMIs) is given by less conservative Wirtinger-based integral inequality approach. Three numerical comparative examples are given to verify the superiority of the proposed approach in reducing the conservation of conclusion. For the first example about closed-loop control systems with interval time-varying delays, the proposed robust stability criterion could get MADB (Maximum Allowable Delay Bound) about 0.3 more than the best results in the previous literature; and, for two other uncertain systems with interval time-varying delays, the MADB results obtained by the proposed method are better than those in the previous literature by about 0.045 and 0.054, respectively. All the example results obtained in this paper clearly show that our approach is better than other existing methods.<\/jats:p>","DOI":"10.1155\/2020\/8841137","type":"journal-article","created":{"date-parts":[[2020,12,10]],"date-time":"2020-12-10T19:22:26Z","timestamp":1607628146000},"page":"1-13","source":"Crossref","is-referenced-by-count":2,"title":["Novel Robust Stability Criteria of Uncertain Systems with Interval Time-Varying Delay Based on Time-Delay Segmentation Method and Multiple Integrals Functional"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4361-0151","authenticated-orcid":true,"given":"Xing","family":"He","sequence":"first","affiliation":[{"name":"School of Information and Control Engineering, Xi\u2019an University of Architecture and Technology, Xi\u2019an 710055, Shaanxi, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5169-962X","authenticated-orcid":true,"given":"Li-Jun","family":"Song","sequence":"additional","affiliation":[{"name":"School of Information and Control Engineering, Xi\u2019an University of Architecture and Technology, Xi\u2019an 710055, Shaanxi, China"}]},{"given":"Yu-Bin","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Automation, Xi\u2019an Research Institute of High-Technology, Xi\u2019an 710025, Shaanxi, China"}]},{"given":"Zi-Yu","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Information and Control Engineering, Xi\u2019an University of Architecture and Technology, Xi\u2019an 710055, Shaanxi, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/j.isatra.2014.05.006"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jfranklin.2020.02.038"},{"issue":"2","key":"3","doi-asserted-by":"crossref","first-page":"492","DOI":"10.1080\/00207721.2014.891674","article-title":"Improved results for linear discrete-time systems with an interval time-varying input delay","volume":"47","author":"J.
