Abstract
The invention relates to a control system for at least one actuator (6) for the cowlings of a thrust inverter 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).
