Post-doc position on FDIR in autonomous space vehicles
The research fits into the framework of the SIRASAS (Innovative and
robust strategies for spacecraft autonomy, https://extranet.ims-bordeaux.fr/External/SIRASAS)
project, which is supported by the Research Foundation for
Aeronautics and Space (FRAE) and agreed by the competitiveness pole
AESE (Aerospace Valley, strategic activity domain Embedded Systems,
federated program Diagnosis). It received funding for 3 years from
November 2007. SIRASAS is coordinated by IMS (Bordeaux) and the
partners are: SATIE (ENS Cachan), LAAS-CNRS (Toulouse), CRAN (Nancy),
LRI (Univ. Paris-Sud, Orsay), ONERA (Toulouse), CNES (Toulouse),
Airbus France (Toulouse) and Thales Alenia Space (Cannes).
The objective of the project is to promote innovative and robust
technologies that could significantly increase spacecraft autonomy. It
addresses the model-based Fault Detection, Identification and Recovery
(FDIR) challenges for G&C (Guidance and Control). The actions
undertaken within SIRASAS aim at overcoming the dead zone between the
scientific advanced methods proposed by the academic and research
communities and the technological solutions demanded by the aerospace
industry, with stringent operational constraints. More precisely, in
the space domain, the objective is to reduce needs for permanent
control by ground operators, to equip the space system with autonomous
FDIR capacities and to increase the availability of the system.
The space application scenario is the terminal phase of rendez-vous
for the Mars Sample Return mission, for which simulators in Simulink
are available. During the two first years of the project, solutions
for early fault detection and location in this scenario have been
designed by the partners. During this third year, LRI will work in
cooperation with LAAS and ONERA on general FDIR techniques in a
context of autonomy, focusing on functional reconfiguration. A report
will be produced, synthesizing the existing works, in particular those
from NASA (Livingstone, HYDE), and proposing realistic solutions or
lines of research. The post-doc will have to study existing works, to
propose embedded autonomous FDIR functions and to test some of them
with available simulators. He/she will have to do this in tight
collaboration with LAAS and ONERA.
He/she will work in the IASI (Artificial Intelligence and Inference
Systems: http://www.lri.fr/equipe.php?eq=8) research group of LRI, the
laboratory of Computer Science of the University Paris-Sud 11 and
CNRS, located at Orsay in the South of Paris. IASI is also a joint
team with Gemo project of INRIA Saclay - Île-de-France. The
responsible of LRI inside this project is Prof. Philippe Dague.
Candidates should have:
- a PhD thesis in Computer Science or Control Theory;
- good knowledge of model-based diagnosis techniques in AI and Control
Theory, and of modeling formalisms for discrete-event and hybrid
systems;
- programming experience in Simulink.
Previous knowledge or experience in spacecraft domain would be welcome.
The position is available from beginning of January to end of October
2010.
Salary is from 2300 euros gross/month.
