First, a novel prescribed-performance fault-tolerant control framework is developed by incorporating a funnel function, a barrier Lyapunov function, and a bounded estimation mechanism to address the issue of multiple constrained nonlinear disturbances. Second, the proposed strategy offers two key improvements: (1) adequate compensation for the coupled effects of actuator faults and dead-zone nonlinearities, and (2) guaranteed globally prescribed transient performance, making the settling time and tracking accuracy independent of initial conditions and design parameters. Lastly, simulation results verify the approach\u2019s effectiveness, showing rapid convergence within 0.8 s and a tracking error bounded by \u00b10.05, thus surpassing traditional methods.<\/jats:p>","DOI":"10.3390\/sym17111915","type":"journal-article","created":{"date-parts":[[2025,11,10]],"date-time":"2025-11-10T10:35:31Z","timestamp":1762770931000},"page":"1915","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Prescribed Performance Adaptive Fault-Tolerant Control for Nonlinear System with Actuator Faults and Dead Zones"],"prefix":"10.3390","volume":"17","author":[{"given":"Zhenlin","family":"Wang","sequence":"first","affiliation":[{"name":"Division of Electronics and Informatics, Gunma University, Kiryu 376-8515, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3338-2418","authenticated-orcid":false,"given":"Seiji","family":"Hashimoto","sequence":"additional","affiliation":[{"name":"Division of Electronics and Informatics, Gunma University, Kiryu 376-8515, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuyuki","family":"Kurita","sequence":"additional","affiliation":[{"name":"Department of Surgery, Baylor College of Medicine, 1 Baylor Plz, Houston, TX 77030, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pengqiang","family":"Nie","sequence":"additional","affiliation":[{"name":"Division of Electronics and Informatics, Gunma University, Kiryu 376-8515, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Song","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Automation, Jiangsu University of Science and Technology, Zhenjiang 212000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4460-8694","authenticated-orcid":false,"given":"Takahiro","family":"Kawaguchi","sequence":"additional","affiliation":[{"name":"Division of Electronics and Informatics, Gunma University, Kiryu 376-8515, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11617","DOI":"10.1109\/LRA.2022.3203224","article-title":"Direction and Trajectory Tracking Control for Nonholonomic Spherical Robot by Combining Sliding Mode Controller and Model Prediction Controller","volume":"7","author":"Liu","year":"2022","journal-title":"IEEE Robot.
