By designing a finite-time disturbance observer and using the technique based on the addition of a power integrator, a composite controller is proposed to guarantee leader-following rendezvous in finite time. Moreover, an appropriate Lyapunov potential function is proposed to ensure connectivity preservation. A numerical example is provided to illustrate the effectiveness of the theoretical results.<\/jats:p>","DOI":"10.1177\/0142331217693918","type":"journal-article","created":{"date-parts":[[2017,8,1]],"date-time":"2017-08-01T05:23:18Z","timestamp":1501564998000},"page":"1766-1775","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Finite-time leader-following rendezvous for Euler\u2013Lagrange multi-agent systems with an uncertain leader"],"prefix":"10.1177","volume":"40","author":[{"given":"Ping","family":"Li","sequence":"first","affiliation":[{"name":"School of Automation, Nanjing University of Science and Technology, Nanjing, China"}]},{"given":"Shengyuan","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Automation, Nanjing University of Science and Technology, Nanjing, China"}]},{"given":"Yuming","family":"Chu","sequence":"additional","affiliation":[{"name":"School of Science, Huzhou Teachers College, Huzhou, China"}]},{"given":"Weimin","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Science, Nanjing University of Science and Technology, Nanjing, China"}]},{"given":"Zhengqiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering and Automation, Qufu Normal University, Rizhao, China"}]}],"member":"179","published-online":{"date-parts":[[2017,8,1]]},"reference":[{"key":"bibr1-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1109\/9.668834"},{"key":"bibr2-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1109\/TSMCB.2010.2095497"},{"key":"bibr3-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1016\/j.automatica.2014.03.001"},{"key":"bibr4-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cta.2009.0229"},{"key":"bibr5-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1109\/CDC.2014.7039852"},{"key":"bibr6-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1016\/j.automatica.2015.03.006"},{"key":"bibr7-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1002\/rnc.3090"},{"key":"bibr8-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1016\/j.automatica.2006.02.013"},{"key":"bibr9-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1002\/rnc.3263"},{"key":"bibr10-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2014.2324212"},{"key":"bibr11-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1002\/rnc.3124"},{"key":"bibr12-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1177\/0142331213513605"},{"key":"bibr13-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2005.864190"},{"key":"bibr14-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2004.834113"},{"key":"bibr15-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1109\/ICICIP.2010.5565222"},{"key":"bibr16-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1109\/9.935058"},{"key":"bibr17-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2008.924961"},{"key":"bibr18-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1016\/j.automatica.2007.01.008"},{"key":"bibr19-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1016\/j.automatica.2015.04.015"},{"key":"bibr20-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1016\/j.sysconle.2013.02.013"},{"key":"bibr21-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1049\/iet-cta.2013.0869"},{"key":"bibr22-0142331217693918","doi-asserted-by":"publisher","DOI":"10.1016\/j.automatica.2014.07.019"},{"key":"bibr23-0142331217693918","unstructured":"Zhang Y, Cui G, Zhuang G, et al.
