Abstract
In this paper, two novel approaches for detection of faults in dynamical systems are presented. Both approaches are based on set-membership identification, a system identification strategy which seeks to identify a set of parameters rather than a single point estimate. The optimal volume ellipsoid algorithm (OVE) and the OVE algorithm for time-varying systems (OVETV) will be utilized for set-membership identification. The first detection strategy uses a consistency check which is integral to the OVE and OVETV algorithms. The second approach combines an ellipsoid intersection test with the OVETV algorithm.
