First, the system model of joint structure instead of a single maglev unit is established, then a state observer is designed to observe the movement of a suspension frame, and a control strategy based on linear quadratic optimal control method is proposed. This control strategy based on a joint structure model is advantageous in suspension performance in the presence of external disturbances. Comparative simulation results show that this control strategy has a better performance under the condition of external force disturbance. An experiment on single-carriage high-speed permanent magnet electromagnetic suspension system maglev train is conducted on a 1.5-km test line; the performance is satisfactory for employment.<\/jats:p>","DOI":"10.1177\/0959651817750520","type":"journal-article","created":{"date-parts":[[2018,1,23]],"date-time":"2018-01-23T05:30:50Z","timestamp":1516685450000},"page":"315-323","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":23,"title":["Levitation control of permanent magnet electromagnetic hybrid suspension maglev train"],"prefix":"10.1177","volume":"232","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5094-0506","authenticated-orcid":false,"given":"Zhiqiang","family":"Wang","sequence":"first","affiliation":[{"name":"School of Mechatronics Engineering and Automation, National University of Defense Technology, Changsha, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiqiang","family":"Long","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering and Automation, National University of Defense Technology, Changsha, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaolong","family":"Li","sequence":"additional","affiliation":[{"name":"School of Mechatronics Engineering and Automation, National University of Defense Technology, Changsha, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,1,23]]},"reference":[{"key":"bibr1-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-662-45673-6_1"},{"key":"bibr2-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1109\/TMAG.2006.875842"},{"key":"bibr3-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1177\/0954409712441740"},{"key":"bibr4-0959651817750520","volume-title":"The M3 urban transportation system","author":"Thornton R.","year":"2003"},{"key":"bibr5-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1109\/TASC.2006.871345"},{"key":"bibr6-0959651817750520","first-page":"76","volume-title":"Proceedings of the 18th international conference on magnetically levitated systems and linear drives (MAGLEV 2004)","author":"Yasuda Y"},{"key":"bibr7-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1109\/20.996030"},{"key":"bibr8-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1109\/CEEJ.1978.6591130"},{"key":"bibr9-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1049\/ep.1971.0027"},{"key":"bibr10-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1109\/TMAG.1980.1060564"},{"key":"bibr11-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1109\/25.45486"},{"key":"bibr12-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1109\/20.334204"},{"key":"bibr13-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1049\/iet-est.2010.0018"},{"key":"bibr14-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1109\/TEC.2014.2388155"},{"key":"bibr15-0959651817750520","doi-asserted-by":"publisher","DOI":"10.1109\/20.250751"},{"key":"bibr16-0959651817750520","first-page":"1019","volume-title":"Proceedings of the 18th international conference on magnetically levitated systems and linear drives (MAGLEV 2004)","author":"Xu Z"},{"key":"bibr17-0959651817750520","first-page":"50","volume":"27","author":"Li W","year":"2005","journal-title":"J China Railw Soc"},{"key":"bibr18-0959651817750520","first-page":"74","volume-title":"Proceedings of the 8th international symposium on magnetic suspension technology","author":"Li Y"},{"key":"bibr19-0959651817750520","first-page":"169","volume-title":"Proceedings of the ISECS international colloquium on computing, communication, control, and management, 2009 (CCCM 2009)","author":"Qiang W"},{"key":"bibr20-0959651817750520","unstructured":"Guangwei S, Meisinger IR, Gang S.
