Abstract

This paper presents new results in observer-based robust fault reconstruction for uncertain systems using cascaded sliding mode observers. Signals from an observer are used as the output of a fictitious system whose input is the fault. Then an observer is implemented for the fictitious system. This process is repeated until the first Markov parameter of the fictitious system is full rank. The result is that robust fault reconstruction can be carried out for a wider class of systems. An example verifies the effectiveness of the proposed scheme.
