Abstract :
A geometrical interpretation of the generalized likelihood test (GLT) approach to sensor failue detection and isolation (FDI) is provided, and analytical expressions are derived to evaluate FDI performance parameters of interest. These results are used to determine the FDI performance which can be achieved when various FDI decision strategies are applied to two redundant sensor configurations: a conical array of five single degree-of-freedom sensors and a dodecahedron array of six single degree-of-freedom sensors.
