摘      要：This paper addresses the problem of Fault Detection and Isolation （FDI） of switching systems where faulty behaviours are represented as faulty *** objectives of the on-line FDI are to identify accurately the current mode and to estimate precisely the switching time.A data-based method is considered here to generate residuals that will be used for *** discernibility condition between modes is *** is claimed in the literature that discernibility conditions are necessary for switching ***,it is shown in this paper that the switching may be detected with the proposed residuals even if the modes are not *** conditions between modes are established and are shown to be different from discernibility ones.A simulation example is provided to illustrate this important result.
