With the requirements of miniaturization and high speed of rotating machinery, the rotor of the maglev motor will operate above the bending critical speed, and the critical vibration control of the flexible rotor is facing challenges. In order to solve the problem of the critical vibration suppression of the maglev high-speed motor, the system model of the maglev motor is established, the rotordynamics of the flexible rotor are analyzed and the rotor model is modal truncated to reduce the order. Then, the \u03bc\u2013controller is designed, and the weighting functions are designed to deal with the modal uncertainty. Finally, an experimental platform of the maglev motor with the flexible rotor is built to verify the effect of the \u03bc\u2013control on the suppression of the critical vibration of the maglev rotor.<\/jats:p>","DOI":"10.3390\/s22228692","type":"journal-article","created":{"date-parts":[[2022,11,10]],"date-time":"2022-11-10T21:22:02Z","timestamp":1668115322000},"page":"8692","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Critical Vibration and Control of the Maglev High-Speed Motor Based on \u03bc\u2013Synthesis Control"],"prefix":"10.3390","volume":"22","author":[{"given":"Yefa","family":"Hu","sequence":"first","affiliation":[{"name":"School of Mechanical & Electronic Engineering, Wuhan University of Technology, Wuhan 430070, China"},{"name":"Shenzhen Research Institute, Wuhan University of Technology, Shenzhen 518057, China"},{"name":"Hubei Provincial Engineering Technology Research Center for Magnetic Suspension, School of Mechanical & Electronic Engineering, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0682-5666","authenticated-orcid":false,"given":"Kezhen","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Mechanical & Electronic Engineering, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huachun","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Mechanical & Electronic Engineering, Wuhan University of Technology, Wuhan 430070, China"},{"name":"Shenzhen Research Institute, Wuhan University of Technology, Shenzhen 518057, China"},{"name":"Hubei Provincial Engineering Technology Research Center for Magnetic Suspension, School of Mechanical & Electronic Engineering, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinhua","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Mechanical & Electronic Engineering, Wuhan University of Technology, Wuhan 430070, China"},{"name":"Hubei Provincial Engineering Technology Research Center for Magnetic Suspension, School of Mechanical & Electronic Engineering, Wuhan University of Technology, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nianxian","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Machinery and Automation, Wuhan University of Science and Technology, Wuhan 430081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,10]]},"reference":[{"key":"ref_1","first-page":"437","article-title":"Analysis of Quasi-Zero Power Characteristic for a Permanent Magnetic Levitation System With a Variable Flux Path Control Mechanism","volume":"26","author":"Zhao","year":"2021","journal-title":"IEEE-ASME Trans.
