Compared with the classical state\u2010observer\u2010based approaches, the calculations needed in the new method only involve a few addition and logical operations. The simplicity and reliability of the new method makes itself especially useful for fault detection of current sensors in real\u2010time control systems with limited computational capability, e.g., single\u2010chip microcomputers (SCM) or field programmable gate arrays (FPGA). The experimental results on the basis of a FPGA controller have validated the feasibility and robustness of the proposed FDI approach.<\/jats:p>","DOI":"10.1155\/2021\/9955348","type":"journal-article","created":{"date-parts":[[2021,7,28]],"date-time":"2021-07-28T19:50:06Z","timestamp":1627501806000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Sign Logic\u2010Based Method of Current Sensor Fault Detection for PMSM Drivers"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3064-665X","authenticated-orcid":false,"given":"Chuangqiang","family":"Guo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0375-6765","authenticated-orcid":false,"given":"Chunya","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hong","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,7,28]]},"reference":[{"key":"e_1_2_9_1_2","first-page":"59","article-title":"Fault-tolerant control focusing on phase current sensors of permanent magnet synchronous machine drive systems based on hysteresis current control","volume":"32","author":"Wang W.","year":"2012","journal-title":"Proceedings of the Chinese Society of Electrical Engineering"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1049\/el.2016.2198"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2013.2244537"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TPEL.2011.2140333"},{"key":"e_1_2_9_5_2","doi-asserted-by":"crossref","unstructured":"ZhangG.
