Research ArticleOpen accessIn the abstractSliding Mode Observer-Based Fault Reconstruction for Uncertain Linear SystemsSlim Dhahri, Faycal Ben Hmida, Anis SellamiProblem statement: Fault reconstruction scheme is different from the majority of Fault Detection and Isolation (FDI) methods described in the literature in the sense that it not only detects and isolates the fault, but provides an estimate of the fault. This approach is very useful for incipient faults and slow drifts, which are very difficult to detect. Also, this approach … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 8 Sep 2011 · 7,350 accessesView PDFCite
