MBSE4FDIR



Brief Description:

The Model Based Engineering for Failure Detection, Isolation and Recovery (MBSE4FDIR) project aims to capture, develop and realize FDIR concepts using modern MBSE concepts.

Project Description:

Up to today even well designed systems are not free of errors, but a spacecraft needs to deal with these unknown faults to some extent. To raise trust in handling system failures, reliability engineering applies Failure Detection, Isolation and Recovery (FDIR) concepts.

MBSE4FDIR is an internal DLR-Project aiming to capture FDIR concepts using modern MBSE methodologies. With this research we strife to conceive a holistic model for space systems consisting of software and hardware on the one hand and the satellite and the ground segment on the other hand. Of further interest are also the development of new approaches for verifying and validating FDIR solutions. For this purpose methods from the areas of simulation and formal verification are employed.

Furthermore, the on “Virtual Satellite 4” based software “VirSat FDIR” is being developed within the context of the MBSE4FDIR project with the goal of providing automated, software tool support for conceiving and analyzing FDIR Models.

DLR Simulation and Software Technology Tasks

  • Capturing and unifying DLR internal FDIR methodologies and processes
  • Development of MBSE Models for representing FDIR concepts
  • Development of the “Virtual Satellite 4” based software “VirSat FDIR” for FDIR design
  • Automatic analysis of the models on the basis of formal methods
