On fault diagnosis of satellite attitude control system based on ARRs

Based on the analytical redundancy relations (ARRs), the fault diagnosability analysis and fault diagnosis problem of satellite attitude control system (ACS) is researched in this paper. To make sure the completeness of the ARRs set, the ARRs generation method utilizing the rank operation is proposed. And then the multilevel fault diagnosability of satellite attitude control system is supplied including the component-level, the subsystem-level and the system-level. The ARRs optimization method based on the binary particle swarm optimization as well as the fault diagnosis method dependent on the incidence matrix is given in this paper. Finally, simulation results of the satellite ACS with typical configuration are presented to illustrate the efficiency of the proposed method.
