Compared with the existing results for adaptive fuzzy control, the stochastic nonlinear systems investigated in this paper are much more complex since the systems not only have distributed state time-varying delays in the noise jamming intensity terms but also have the time-varying delays in the input signals. During the controller design procedure, through appropriate assumptions and a state transformation the system with time-varying input delay can be easily transformed into a system without input delay. The other main advantage is that quadratic functions are used as Lyapunov functions to analyze the stability of systems, other than the fourth moment approach proposed by H. Deng and M. Krstic, and the hyperbolic tangent functions are introduced to deal with the Hessian terms. The proposed adaptive fuzzy controller guarantees that all the signals in the closed-loop system are bounded in probability and the tracking error can converge to a small residual set around the origin in the mean square sense.<\/jats:p>","DOI":"10.1142\/s0218488518500071","type":"journal-article","created":{"date-parts":[[2018,2,1]],"date-time":"2018-02-01T07:22:01Z","timestamp":1517469721000},"page":"109-142","source":"Crossref","is-referenced-by-count":6,"title":["Adaptive Fuzzy Tracking Control for Stochastic Nonlinear Systems with Time-Varying Input Delays Using the Quadratic Functions"],"prefix":"10.1142","volume":"26","author":[{"given":"Hongyun","family":"Yue","sequence":"first","affiliation":[{"name":"School of Science, Xi\u2019an University of Architecture and Technology, Xi\u2019an 710055, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junmin","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Applied Mathematics, Xidian University, Xi\u2019an 710071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiarong","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Science, Xi\u2019an University of Architecture and Technology, Xi\u2019an 710055, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Science, Xi\u2019an University of Architecture and Technology, Xi\u2019an 710055, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2018,1,31]]},"reference":[{"key":"p_1","doi-asserted-by":"publisher","DOI":"10.1109\/9.704978"},{"key":"p_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2002.803553"},{"key":"p_3","doi-asserted-by":"publisher","DOI":"10.1137\/S0363012903439185"},{"key":"p_4","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-6911(97)00067-4"},{"key":"p_5","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2011.11.004"},{"key":"p_6","doi-asserted-by":"publisher","DOI":"10.1002\/rnc.1177"},{"key":"p_7","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2013.09.005"},{"key":"p_8","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2013.06.036"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.1109\/TFUZZ.2014.2348017"},{"key":"p_10","doi-asserted-by":"publisher","DOI":"10.1109\/TCYB.2014.2363073"},{"key":"p_11","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2013.09.047"},{"key":"p_12","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2005.863501"},{"key":"p_13","first-page":"18","volume":"10","author":"Yu J.
