Zusammenfassung
In this paper an observer-based fault detection approach for a class
of nonlinear systems, which can be modeled by Takagi-Sugeno (TS)
fuzzy models, is presented. We propose a sliding mode fuzzy observer
that deals with bounded uncertainties in the plant and allows fault
estimation based on an equivalent output error injection approach.
Necessary conditions for the existence of the robust observer are
derived from sliding mode theory . Stability is ensured by linear
matrix inequality (LMI) based sufficient conditions. An illustrative
example demonstrates the effectiveness of the proposed scheme.
