Abstract

This chapter addresses the problem of Fault Detection and Isolation (FDI) of switching systems where faulty behaviors are represented as faulty modes. The objectives of the online FDI are to identify accurately the current mode and to estimate the switching time. A data-based method is considered here to generate residuals for FDI. Conditions of two important properties, namely discernability between modes and switching detectability, are established. These conditions are different for the two properties. More specifically, it will be shown that a switching occurrence may be detected even if the two considered modes are not discernible. A vehicle rollover prevention example is provided for illustration purpose.
