As a result, the pancreas cannot produce adequate insulin, and the glucose enters the cells to produce energy. To elevate the glycaemic concentration, sufficient amount of insulin should be taken orally or injected into the human body. Artificial pancreas is a device that automatically regulates the level of body insulin by injecting the requisite amount of insulin into the human body. A finite\u2010time robust feedback controller based on the Extended Bergman Minimal Model is designed here. The controller is designed utilizing the backstepping approach and is robust against the unknown external disturbance and parametric uncertainties. The stability of the system is proved using the Lyapunov theorem. The controller is exponentially stable and hence provides the finite\u2010time convergence of the blood glucose concentration to its desired magnitude. The effectiveness of the proposed control method is shown through simulation in MATLAB\/Simulink environment via comparisons with previous studies.<\/jats:p>","DOI":"10.1049\/syb2.12032","type":"journal-article","created":{"date-parts":[[2021,7,8]],"date-time":"2021-07-08T05:42:05Z","timestamp":1625722925000},"page":"173-183","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Variable structure robust controller design for blood glucose regulation for type 1 diabetic patients: A backstepping approach"],"prefix":"10.1049","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2925-8916","authenticated-orcid":false,"given":"Mohamadreza","family":"Homayounzade","sequence":"first","affiliation":[{"name":"Mechanical Engineering Department Faculty of Engineering Fasa University  Fasa Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"265","published-online":{"date-parts":[[2021,7,8]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.4103\/2468-8827.184853"},{"key":"e_1_2_9_3_1","volume-title":"National Diabetes Statistics Report.
