Study of an adaptive reconfigurable control scheme for tailless advanced fighter aircraft (TAFA) in the presence of wing damage

We describe the implementation of the multiple model-based failure detection and identification (FDI) and adaptive reconfigurable control (ARC) algorithms of Boskovic and Mehra (see Proceeding of the 1998 Conference on Decision and Control, Tampa, FL, 1998) anf of Boskovic, Li, Rago and Mehra (see Technical report, Scientific Systems Co., Inc., 1999) in the nonlinear 6 DOF TAFA simulation. Due to the nonlinear nature of the simulation, the implementation and tuning of the algorithms is substantially more complicated than their counterparts in linear simulations. However, the well tuned FDI-ARC achieved excellent performance despite severe flight-critical variations in the aircraft dynamics.
