Previous works in this area have suffered from the uncertainties of the PMSM parameters, which can lead to misdiagnosis. The proposed method estimates the q-axis inductance (Lq) of the faulty PMSM to solve this problem. The proposed method also estimates the faulty phase and the value of G, which serves as an index of the severity of the fault. The q-axis current is used to estimate the faulty phase, the values of G and Lq. For this reason, two open-loop observers and an optimization method based on a particle-swarm are implemented. The q-axis current of a healthy PMSM is estimated by the open-loop observer with the parameters of a healthy PMSM. The Lq estimation significantly compensates for the estimation errors in high-speed operation. The experimental results demonstrate that the proposed method can estimate the faulty phase, G, and Lq besides exhibiting robustness against parameter uncertainties.<\/jats:p>","DOI":"10.3390\/s151129452","type":"journal-article","created":{"date-parts":[[2015,11,24]],"date-time":"2015-11-24T01:57:02Z","timestamp":1448330222000},"page":"29452-29466","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Robust Diagnosis Method Based on Parameter Estimation for an Interturn Short-Circuit Fault in Multipole PMSM under High-Speed Operation"],"prefix":"10.3390","volume":"15","author":[{"given":"Jewon","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, Pohang University of Science and Technology (POSTECH), Room 304, LG Cooperative Electronics Engineering Building, 77 Cheongam-Ro, Nam-Gu, Pohang 37673, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seokbae","family":"Moon","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Pohang University of Science and Technology (POSTECH), Room 304, LG Cooperative Electronics Engineering Building, 77 Cheongam-Ro, Nam-Gu, Pohang 37673, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyeyun","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Pohang University of Science and Technology (POSTECH), Room 304, LG Cooperative Electronics Engineering Building, 77 Cheongam-Ro, Nam-Gu, Pohang 37673, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Pohang University of Science and Technology (POSTECH), Room 304, LG Cooperative Electronics Engineering Building, 77 Cheongam-Ro, Nam-Gu, Pohang 37673, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2015,11,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16950","DOI":"10.3390\/s131216950","article-title":"Fault Diagnosis of Rotating Machinery Based on an Adaptive Ensemble Empirical Mode Decomposition","volume":"13","author":"Lei","year":"2013","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"11027","DOI":"10.3390\/s150511027","article-title":"Current Sensor Fault Diagnosis Based on a Sliding Mode Observer for PMSM Driven Systems","volume":"15","author":"Huang","year":"2015","journal-title":"Sensors"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"11989","DOI":"10.3390\/s120911989","article-title":"Smart Sensor for Online Detection of Multiple-Combined Faults in VSD-Fed Induction Motors","volume":"12","year":"2012","journal-title":"Sensors"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"10448","DOI":"10.3390\/s101110448","article-title":"An Online Universal Diagnosis Procedure Using Two External Flux Sensors Applied to the AC Electrical Rotating Machines","volume":"10","author":"Pusca","year":"2010","journal-title":"Sensors"},{"key":"ref_5","doi-asserted-by":"crossref","unstructured":"Zhou, H., Yu, B., Lin, Z., Wang, H., Li, X., and Zheng, P.
