Active vibration isolation (AVI) has been extensively studied by many scholars. However, traditional actuators suffer from contact friction and response delay; feedback and feedforward control alone have performance bottlenecks. As a result, the low-frequency tracking and mid-frequency isolation performance of CMG AVI are severely limited. Therefore, this paper proposes a magnetic levitation vibration isolation system (MLVIS) with composite control to optimize the tracking and AVI performance. In terms of structure, a magnetic levitation actuator is used to eliminate slow response and friction hysteresis. For the control algorithm, a composite strategy integrating integral force feedback and filtered-x recursive least squares is adopted. Through mutual compensation between the two control methods, this composite strategy mitigates the inherent time delay of feedback control and the instability of feedforward control. Experimental results show that the tracking error in the low-frequency band is 2.71% and 11.67% under single- and dual-frequency excitation, respectively, while 91.86% attenuation of the natural-frequency vibration amplitude is achieved in the mid-frequency band. These results verify the tracking and AVI performance of the MLVIS.<\/jats:p>","DOI":"10.1063\/5.0313768","type":"journal-article","created":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T12:43:05Z","timestamp":1783687385000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Vibration isolation and low-frequency tracking based on magnetic levitation with composite control"],"prefix":"10.1063","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5587-618X","authenticated-orcid":false,"given":"Shibo","family":"Fu","sequence":"first","affiliation":[{"name":"School of Mechatronics Engineering and Automation, Shanghai University 1 , Shanghai 200444,","place":["China"]},{"name":"Shanghai Collaborative Innovation Center of Intelligent Sensing Chip Technology 2 , Shanghai 200444,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1756-1405","authenticated-orcid":false,"given":"Min","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering and Automation, Shanghai University 1 , Shanghai 200444,","place":["China"]},{"name":"Shanghai Collaborative Innovation Center of Intelligent Sensing Chip Technology 2 , Shanghai 200444,","place":["China"]},{"name":"Shangda General Intelligent Robotics Research Institute 3 , Baoshan District, Shanghai 200444,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-0357-8278","authenticated-orcid":false,"given":"Di","family":"Zhang","sequence":"additional","affiliation":[{"name":"Beijing Xiaomi Mobile Software Co., Ltd. 4 , Beijing 100085,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cai","family":"Xiao","sequence":"additional","affiliation":[{"name":"Beijing Xiaomi Mobile Software Co., Ltd. 4 , Beijing 100085,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiheng","family":"Ding","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering and Automation, Shanghai University 1 , Shanghai 200444,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8019-6765","authenticated-orcid":false,"given":"Yi","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering and Automation, Shanghai University 1 , Shanghai 200444,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huayan","family":"Pu","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering and Automation, Shanghai University 1 , Shanghai 200444,","place":["China"]},{"name":"State Key Laboratory of Mechanical Transmissions, Chongqing University 5 , Chongqing 400044,","place":["China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,7,10]]},"reference":[{"key":"2026071008425518200_c1","doi-asserted-by":"publisher","first-page":"105677","DOI":"10.1016\/j.ast.2019.105677","article-title":"Quaternion based linear time-varying model predictive attitude control for satellites with two reaction wheels","volume":"98","year":"2020","journal-title":"Aerosp.
