CA 2693355

The invention relates to a control system for at least one actuator (6) for the cowlings of a thrust reverser in a turbojet engine that comprises an assembly of actuation and/or control components. A control means (9) is provided for detecting the failure of an actuation and/or control component (7, 16, 13), for determining the blocking or non-blocking character of the failure for the system operation and, in case of a non-blocking failure, for switching from a nominal operation mode to a failure-adaptation operation mode in which the failure of the actuation and/or control component (7, 16, 13) is compensated at least partially by a modified instruction of the other actuation and/or control components (7, 16, 13).

L'invention concerne un système de commande d'au moins un actionneur (6) de capots d'un inverseur de poussée pour turboréacteur comprenant un ensemble de composants d'actionnement et/ou de contrôle. Des moyens de commande (9) sont agencés pour détecter une panne d'un composant d'actionnement et/ou de contrôle (7, 16, 13), pour déterminer le caractère bloquant ou non bloquant de la panne pour le fonctionnement du système et, en cas de panne non bloquante, pour passer d'un mode de fonctionnement normal à un mode de fonctionnement d'accommodation de panne dans lequel la panne du composant d'actionnement et/ou de contrôle (7, 16, 13) est compensée au moins partiellement par une commande modifiée des autres composants d'actionnement et/ou de contrôle (7, 16, 13).
