Abstract

The diagnosability is the inherent property of spacecraft control system, mainly including the fault detectability and isolability. Analysis of diagnosability in the system design stage contributes to reduce the failure risks for it reveal the relation between system structure and faults, which suggests a easier way to design a fault diagnosis algorithm and devoting to a necessary redundancy and safety. The model uncertainties and process noise affect the diagnosability evaluation but still gain deficient attention in current researches, in this work we consider a method using Energy-statistics to evaluate the system diagnosability with model uncertainties as well as process noise, propose the definition and the calculation of fault detectability and isolability. 1
