Summary:

Fault detection and identification system generally uses state observers to generate redundant signals. State observers need sensor measure as input signal but sensor measure contains noise and this noise can damage redundant signals. In this paper, we will show how the sensor noise can affect redundant signals generated by a Luenberger observer designed to be used in a DOS structure. PI Observer due to its conception can be designed to be robust to sensor noise. We will propose a method using the recursive definition of the determinant of a matrix to design the PI Observer to be used in a DOS structure. Finally, we will show the performance of the PI observer for detecting and identifying faults in sensors with noise in its measurement
