A nonlinear unknown input observer is designed and the output estimation error is used as a residual for fault detection. To deal with the problem of high Lipschitz constants, a modified mean-value theorem is used to express the nonlinear error dynamics as a convex combination of known matrices with time-varying coefficients. Moreover, the disturbance attenuation is performed using a modified H<jats:sub>\u221e<\/jats:sub> criterion. A sufficient condition for the existence of an unknown input observer is obtained using a linear matrix inequality formula, and the observer gains are obtained by solving the corresponding set of inequalities. The advantages of the proposed method are that no a priori assumption on the unknown input is required and that it can be applied to a large class of nonlinear systems. Performances of the proposed approach are shown through the application to a diesel engine model.<\/jats:p>","DOI":"10.2478\/amcs-2013-0042","type":"journal-article","created":{"date-parts":[[2013,10,14]],"date-time":"2013-10-14T20:09:37Z","timestamp":1381781377000},"page":"557-569","source":"Crossref","is-referenced-by-count":14,"title":["Robust nonlinear observer design for actuator fault detection in diesel engines"],"prefix":"10.61822","volume":"23","author":[{"given":"Boulaid","family":"Boulkroune","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Issam","family":"Djemili","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdel","family":"Aitouche","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincent","family":"Cocquempot","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"37438","container-title":["International Journal of Applied Mathematics and Computer Science"],"original-title":[],"link":[{"URL":"http:\/\/content.sciendo.com\/view\/journals\/amcs\/23\/3\/article-p557.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.degruyter.com\/view\/j\/amcs.2013.23.issue-3\/amcs-2013-0042\/amcs-2013-0042.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,2,29]],"date-time":"2024-02-29T10:28:10Z","timestamp":1709202490000},"score":1,"resource":{"primary":{"URL":"https:\/\/content.sciendo.com\/doi\/10.2478\/amcs-2013-0042"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,9,1]]},"references-count":0,"journal-issue":{"issue":"3"},"URL":"https:\/\/doi.org\/10.2478\/amcs-2013-0042","relation":{},"ISSN":["2083-8492","1641-876X"],"issn-type":[{"value":"2083-8492","type":"electronic"},{"value":"1641-876X","type":"print"}],"subject":[],"published":{"date-parts":[[2013,9,1]]}}}
