Model-integrated toolset for fault detection, isolation and recovery (FDIR)

Fault detection, isolation and recovery (FDIR) functions are essential components of complex engineering systems. The design, validation, implementation, deployment and maintenance of FDIR systems are extremely information intensive tests requiring in-depth knowledge of the engineering system. The paper gives an overview of a model-integrated toolset supporting FDIR from design, into post deployment. The toolset is used for development of large, complex spacecraft systems during the engineering design phase.
