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, 
  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: 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  

- 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  

Salary is from 2300 euros gross/month.
