摘　　要：介绍了一个自修复飞行控制系统故障检测和隔离实时工程软件系统,该系统按照软件工程规范、采用等价空间法和残差向量的概率信息融合法研制和开发,不仅能对飞行控制系统的突变故障——作动器卡死故障和控制舵面损伤故障进行实时检测和隔离,而且具有良好的用户界面。仿真研究表明该软件系统具有良好的鲁棒性和实时性。In this paper,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 for the failure of actuators' failures and single control surface's failures.Finally,test results based on the simulated data prove the validity of the theory,the robust and real time property of the developed software.
