Principles of self-maintenance in an on-board architecture including active diagnosis

This article presents some principles for selfmaintenance in an on-board architecture that embeds on-line active diagnosis. The objective of active diagnosis is to find an action plan that refines the diagnosis without radically changing the mission plan. This leads to the definition of a planning problem that relies on an active diagnoser. According to a decision criterion, the aim is then to find the best conditional plan to reach a diagnosable region of the active diagnoser. The interactions problems between the result of the planning for diagnosis and the mission planning are then detailed and a solution that uses the execution controller of the on-board architecture is proposed.
