This paper addresses the fault detection and isolation (FDI) problem for control surface effectiveness loss (PEL) in self-repairing flight control systems. The proposed FDI algorithm can deal with the case when the control surface damage changes both control matrix B and system matrix A. It is proved that the algorithm is robust to modeling error and disturbance.
