Génération de résidus directionnels pour le diagnostic des systèmes linéaires stochastiques et la commande tolérante aux défauts

Abstract : The main work presented in this document deals with the synthesis of a diagnosis method and a fault tolerant control law for linear stochastic systems. It is divided into two parts: - the first part concerns the design of robust fault detection filter. It has been defined in such a way that the obtained directional residual sensitivity to model and stochastic uncertainties is minimally. This approach is different from the existant ones because the fault detection filter is designed on the basis of a system inversion. - The second part deals with the integration of the fault detection filter into the fault tolerant control law. The deadbeat structure of detection space allows to obtain a fault tolerant control laws having maximum reactivity. Its application to a benchmark defined in the IFATIS project has shown the best reactivity of this control law after the abrupt occurence of both single and multiple faults.
