Therefore, there are many difficulties in the controller design of delta robot. Based on the simplified dynamic model, a nonlinear PD+ controller with nonlinear disturbance observer is proposed for Delta parallel robot in this article, which can realize high-precision trajectory tracking in high-speed and high-acceleration motion. Then, the asymptotic stability of the closed-loop system\u2019s equilibrium point is proven by utilizing Lyapunov techniques and LaSalle\u2019s invariance theorem. It is obvious that the proposed controller is significantly less dependent on the accuracy of the dynamic model. Besides, a disturbance observer based on the generalized momentum is constructed, which can effectively observe and compensate the disturbances. What\u2019s more, the constructed disturbance observer avoids the calculation of the inverse of inertia matrix, which will greatly improve the response speed of the controller. The simulation results show that the proposed controller can assure better trajectory tracking accuracy in high-speed and high-acceleration motion. And the disturbance observer can effectively estimate the disturbance. <\/jats:p><jats:p> The author(s) disclosed receipt of the following financial support for the research, authorship, and\/or publication of this article:This work was supported by the National Natural Science Foundation of China (grant number51474320). <\/jats:p>","DOI":"10.1177\/0959651820974826","type":"journal-article","created":{"date-parts":[[2020,12,15]],"date-time":"2020-12-15T14:06:03Z","timestamp":1608041163000},"page":"1193-1203","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Trajectory tracking control of delta parallel robot based on disturbance observer"],"prefix":"10.1177","volume":"235","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5622-5370","authenticated-orcid":false,"given":"Mingkun","family":"Wu","sequence":"first","affiliation":[{"name":"Key Laboratory of Mechanism Theory and Equipment Design of Ministry of Education, Tianjin University, Tianjin, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5261-8759","authenticated-orcid":false,"given":"Jiangping","family":"Mei","sequence":"additional","affiliation":[{"name":"Key Laboratory of Mechanism Theory and Equipment Design of Ministry of Education, Tianjin University, Tianjin, China"}]},{"given":"Jinlu","family":"Ni","sequence":"additional","affiliation":[{"name":"Key Laboratory of Mechanism Theory and Equipment Design of Ministry of Education, Tianjin University, Tianjin, China"}]},{"given":"Weizhong","family":"Hu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Mechanism Theory and Equipment Design of Ministry of Education, Tianjin University, Tianjin, China"}]}],"member":"179","published-online":{"date-parts":[[2020,12,15]]},"reference":[{"key":"bibr1-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1243\/09596518JSCE604"},{"key":"bibr2-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1016\/j.mechatronics.2007.09.004"},{"key":"bibr3-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1177\/0959651815583423"},{"key":"bibr4-0959651820974826","first-page":"4109","volume-title":"Proceedings of IEEE international conference on robotics and automation","author":"Krut S"},{"key":"bibr5-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1109\/TRA.2004.824690"},{"key":"bibr6-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1115\/1.1711822"},{"key":"bibr7-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1016\/j.mechmachtheory.2013.07.014"},{"key":"bibr8-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1109\/TMECH.2019.2914165"},{"key":"bibr9-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1109\/TCST.2014.2367313"},{"key":"bibr10-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1016\/j.mechmachtheory.2006.06.012"},{"issue":"3","key":"bibr11-0959651820974826","first-page":"1","volume":"46","author":"Zhang LM.","year":"2010","journal-title":"Proc IMechE, Part C: J Mechanical Engineering Science"},{"key":"bibr12-0959651820974826","first-page":"508","volume-title":"Proceedings of IEEE\/ASME international conference on advanced intelligent mechatronics","author":"Pierrot F"},{"key":"bibr13-0959651820974826","first-page":"1875","volume-title":"Proceedings of IEEE international conference on of robotics and automation","author":"Krut S"},{"key":"bibr14-0959651820974826","first-page":"495","volume-title":"Proceedings of the international conference on control applications","author":"Mann GK"},{"key":"bibr15-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4563(199612)13:12<793::AID-ROB2>3.0.CO;2-Q"},{"key":"bibr16-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1007\/s11071-009-9520-1"},{"key":"bibr17-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1177\/0959651817698333"},{"key":"bibr18-0959651820974826","first-page":"66","volume-title":"Proceedings of the international conference on mechatronics, electronics and automotive engineering","author":"Ruiz-Hidalgo NC"},{"key":"bibr19-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1109\/TCST.2006.890297"},{"key":"bibr20-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1109\/TRO.2005.858852"},{"key":"bibr21-0959651820974826","doi-asserted-by":"publisher","DOI":"10.1109\/87.865853"},{"key":"bibr22-0959651820974826","first-page":"1178","volume-title":"Proceedings of 1995 IEEE international conference on robotics and automation","author":"Begon P"},{"key":"bibr23-0959651820974826","first-page":"2934","volume-title":"Proceedings of the 1995 IEEE international conference on systems, man and cybernetics.
