The goal of the control of any robotic system is to achieve high bandwidth, high accuracy of trajectory tracking, and high robustness, whereby the high bandwidth for flexible-joint robot is the most challenging issue. This paper is dedicated to design such a link position controller with high bandwidth based on sliding-mode technique. Then, two control approaches ((1) extended-regular-form approach and (2) the cascaded control structure based on the sliding-mode estimator approach) are presented for the link position tracking control of flexible-joint robot, considering the dynamics of AC-motors in robot joints, and compared with the singular perturbation approach. These two-link position controllers are tested and verified by the simulation studies with different reference trajectories and under different joint stiffness.<\/jats:p>","DOI":"10.1155\/2020\/8861847","type":"journal-article","created":{"date-parts":[[2020,10,28]],"date-time":"2020-10-28T05:20:07Z","timestamp":1603862407000},"page":"1-12","source":"Crossref","is-referenced-by-count":4,"title":["Cascaded Control of Flexible-Joint Robots Based on Sliding-Mode Estimator Approach"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1303-6980","authenticated-orcid":true,"given":"Genliang","family":"Xiong","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Nanchang University, Nanchang XF999, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingxin","family":"Shi","sequence":"additional","affiliation":[{"name":"TTTech Germany GmbH, Shanghai 200070, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haichu","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Nanchang University, Nanchang XF999, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1115\/1.3143860"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/jra.1987.1087102"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/TCST.2017.2749564"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/CDC.1995.479209"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/ROBOT.1998.677024"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/ISIE.2008.4677013"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/tie.2009.2029528"},{"volume-title":"Flexible Joint Robots","year":"1994","author":"M.
