| Abstract: | Based on the physical and mathematical model of spacecraft propulsion system,the application of model based fault diagnosis method to the propulsion system of spacecraft was studied. This method was one of the key technologies in state detection and fault diagnosis expert systems of the propulsion system of spacecraft.The simulation result indicates that the presentation and application of this method makes model based detection and diagnosis of unexpected fault probable in the propulsion system of spacecraft |
