Fault Detection and Isolation of a Cryogenic Rocket Engine Combustion Chamber Using a Parity Space Approach

This paper presents a parity space (PS) approach for fault detection and isolation (FDI) of a cryogenic rocket engine combustion chamber. Nominal and non-nominal simulation data for three engine set points have been provided. The PS approach uses three measurements to generate residuals and a spheri...

Summary:This paper presents a parity space (PS) approach for fault detection and isolation (FDI) of a cryogenic rocket engine combustion chamber. Nominal and non-nominal simulation data for three engine set points have been provided. The PS approach uses three measurements to generate residuals and a spherical transformation to map these residuals to faults. The radial co-ordinate is used for fault detection whereas the azimuthal and polar co-ordinates are used for fault isolation. Evaluation criteria are missed alarms, false alarms, and fault detection time. Although the approach needs a different residual generation method to become more robust, it works very well when compared with the other FDI approaches.
