PROPOSAL NUMBER: 01.04-8944 (For NASA Use Only - Chron: 001057 )
PROPOSAL TITLE: Aircraft Prognostics and Health Management, and Adaptive Reconfigurable Control

The main objective of this project is to design and implement efficient on-line Failure Detection,
Identification and Reconfiguration (FDIR) algorithms for an advanced military aircraft in the
presence of flight-critical control actuator failures. The proposed FDIR system will combine
an advanced decentralized on-line FDI scheme with efficient adaptive reconfigurable control
algorithms to assure effective failure compensation and flight safety improvement despite
severe subsystem and component failures. In order to achieve these objectives, we propose
to carry out the following tasks: (i) Formulate the FDIR problem; (ii) Determine Sensitivity
-To-Failures (STF) of the aircraft dynamic model; (iii) Design an efficient FDIR scheme;
(iv) Evaluation, Verification and Validation (EVV); and (v) Software Tool Development and
Commercialization. It is envisioned that the design will be developed to meet the
specifications arising from the new Intelligent Vehicle Program led by NASA DFRC.
Boeing Phantom Works will provide technical and commercialization support.

Increasingly complex equipment has substantially increased the costs and complexity of maintenance
of modern aircraft and other engineering systems. Hence Health Monitoring, Failure Detection and
Identification (HM-FDI), and Adaptive Reconfigurable Control (ARC) techniques and related software
tools are becoming increasingly important and commercially attractive. A commercial product that
will result from the proposed research is a comprehensive software toolbox for the design of
HM-FDI/ARC systems. Potential applications of the software tool exist in civilian and defense
areas including aircraft, helicopters, jet engines and chemical and process control.
