Robust state estimation for switched systems: Application to fault detection
The presentation deals with state estimation and fault detection for a class of switched linear systems. First, new interval observers are investigated for discrete-time linear parameter varying switched systems, with a known switching signal and measured polytopic parameters. The design conditions include the case of dwell-time switching. Then, robust fault detection approaches are proposed based on interval, zonotopic and ellipsoidal analysis.
