ANALYSE ET SYNTHESE D'UNE ARCHITECTURE COOPERATIVE POUR LA COMMANDE TOLERANTE AUX DEFAUTS - APPLICATION A UN SYSTEME AERONAUTIQUE

Abstract : This thesis discusses the design of an active Fault Tolerant Control (FTC) strategy for improvement of the operational control capability of the safety critical systems. The FTC strategy works in such a way that once a fault is detected by the Fault Detection and Isolation (FDI) unit, a compensation loop is activated for safe recovery. A key feature of the proposed strategy is that the design of the FTC loop is done independently of the nominal control law already in place. For a given application, one can select the appropriate “FTC controller / FDI unit” from the designed set of all admissible FDI/FTC units. The selection is done using performance indicators based on µ-analysis and µg-analysis. Finally, the proposed approach is applied to a faulty scenario of a realistic nonlinear benchmark of a large transport aircraft within European Flight Mechanics Action Group (FM-AG(16)) of GARTEUR program. The goal is to provide a “self-repairing” capability to enable the pilot to land the aircraft safely in the event of a stabilizer fault.
