Fault-tolerant control for complex nonlinear system is an emerging technology intended to provide the designer and operator with flexibility, interoperability, sustainment and reliability under changing operational requirements or mission profiles. Moreover, it is intended to reconfigure online hardware and software to maintain the operational integrity of the system in the event of contingencies (fault/failure modes). The fault tolerant control framework relies on diagnosis and prognostic information knows as Prognostic Health Management (PHM) to reconfigure system components and preserve the operational integrity of the nonlinear system. The hierarchical structure starts at the lowest component level and migrates to the middle system/subsystem level ending with the final mission level. The objectives of PHM is to lead searchers or industrials to strengthen their capability to anticipate the failures occurring in the system.
This session aims at presenting the emergence of PHM theme to FTC and the interaction between these themes.
