| Abstract: | The real-time failure detection and isolation (FDI) software of self-repairing flight control system (SRFCS) is presented according to the specification of software engineering. And an algorithm of parity residuals and the theory of residual vector probability-data fusion are used for detecting the abrupt change failure of SRFCS, especially the failure of actuators'failures and single control surface's failures. Finally, test results based on the simulated data prove the vaildity of the theory, the robust and real time property of the developed software. |
