Compared with the existing research, a novel predefined performance controller is proposed, which relaxes the assumption that the initial error is known. In addition, it is difficult to design the controllers due to input delay and nonaffine properties of the pure-feedback systems, which can be simplified by Pade approximation. Moreover, dynamic surface control and Nussbaum functions are applied to overcome the calculation explosion caused by repeated differentiations and unknown control direction, respectively. Based on the above methods, an adaptive fuzzy predefined performance controller is proposed, and it is proved that all the signals of a closed-loop system are semiglobally uniformly ultimately bounded (SGUUB). The tracking errors converge within a predefined range, while the observer estimation errors converge within a small zero region. Finally, the simulation results demonstrate the effectiveness of the proposed control system.<\/jats:p>","DOI":"10.1155\/2020\/8859328","type":"journal-article","created":{"date-parts":[[2020,12,11]],"date-time":"2020-12-11T00:21:13Z","timestamp":1607646073000},"page":"1-12","source":"Crossref","is-referenced-by-count":1,"title":["Observer-Based Adaptive Fuzzy Predefined Performance Control of a Class of Nonlinear Pure-Feedback Systems with Input Delay"],"prefix":"10.1155","volume":"2020","author":[{"given":"Xin","family":"Li","sequence":"first","affiliation":[{"name":"College of Information Science and Engineering, Northeastern University, Shenyang 110819, China"}]},{"given":"Qiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Information Science and Engineering, Northeastern University, Shenyang 110819, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8303-529X","authenticated-orcid":true,"given":"Dakuo","family":"He","sequence":"additional","affiliation":[{"name":"College of Information Science and Engineering, Northeastern University, Shenyang 110819, China"},{"name":"State Key Laboratory of Synthetical Automation for Process Industries and the College of Information Science and Engineering, Northeastern University, Shenyang 110819, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/0005-1098(95)00147-6"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/s0005-1098(96)00222-1"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.isatra.2013.08.012"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/tcyb.2015.2405616"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1155\/2018\/9765861"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/tsmc.2020.3010642"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2020.08.024"},{"key":"8","doi-asserted-by":"crossref","first-page":"3028","DOI":"10.1109\/ACC.1997.612013","article-title":"Dynamic surface control of nonlinear systems","volume":"5","author":"D.
