Abstract
This paper presents a new fault detection and isolation method which is called
EPSA(Extended Parity Space Approach). This method is particularly suitable for fault
detection and isolation of the system with two faulty sensors. To analyze the situations of
two-faults, the situations are classified into four types. Based on this analysis, the
procedure to isolate the faulty sensors in each situation is suggested. Also how to decide
the threshold value is suggested. The proposed FDI method is verified through Monte
Carlo simulation.
