It introduces a fuzzy adaptive updating law to compensated actuator faults and uses a barrier Lyapunov function (BLF) to handle output constraints in both constrained and unconstrained systems. The method integrates adaptive backstepping and fuzzy logic to manage non-strict feedback challenges and incorporates projection adaptation techniques. The approach incorporates projection adaptation design techniques in its scheme. The controller designed through this method not only ensures finite-time convergence of the system\u2019s output tracking error to the origin but also guarantees compliance with output constraints, even in the face of potentially infinite time-varying actuator failures. The efficacy of this proposed method is corroborated by simulation examples, showcasing its proficiency in managing both actuator faults and output constraints.<\/jats:p>","DOI":"10.1177\/01423312241298397","type":"journal-article","created":{"date-parts":[[2024,12,31]],"date-time":"2024-12-31T04:51:35Z","timestamp":1735620695000},"page":"932-942","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Adaptive finite-time control for non-strict feedback nonlinear systems with infinite number of time-varying actuator failures and output constraints"],"prefix":"10.1177","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6096-845X","authenticated-orcid":false,"given":"Ning","family":"Sheng","sequence":"first","affiliation":[{"name":"College of Control Engineering, Qingdao University of Science and Technology, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-9686-6617","authenticated-orcid":false,"given":"Tianyu","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Control Engineering, Qingdao University of Science and Technology, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qichun","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Creative and Digital Industries, Buckinghamshire New University, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanxue","family":"Cui","sequence":"additional","affiliation":[{"name":"College of Control Engineering, Qingdao University of Science and Technology, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,12,31]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/ACC.1995.531201"},{"issue":"4","key":"e_1_3_2_3_1","first-page":"2438","article-title":"Finite-time stabilization-based adaptive fuzzy control design","volume":"28","author":"Chen B","year":"2020","unstructured":"Chen B, Lin C (2020) Finite-time stabilization-based adaptive fuzzy control design.
