Fault Detection and Diagnosis relying on Set Membership Identification for time varying systems

Abstract: In this paper, a Fault Detection and Diagnosis (FDD) method relying on Set Membership Identification (SMI) is presented, aiming at the detection of multiple abrupt parameter variations for a time varying system. The proposed method utilizes a jump linearly parametrizable model, assuming unknown but bounded measurement noise and parameter perturbations. The objective of SMI is to compute at every time instant the orthotope containing the nominal parameter vector, while a fault is detected at the time instant th… Show more

“…In the literature, several geometric shapes have been used to represent the uncertain parameter set H when using set-membership approaches [10]. For example, in [20,21], the set was approximated by an ellipsoid, Reppa and Tzes [22] have proposed an orthotopic approximation and Vicino and Zappa [23] have used a parallelotopic approximation. When using set-membership identification there is a trade-off between the set size (conservativeness) and the complexity of the identification method.…”
