Abstract :
The absolute reliability of a fault diagnostic device is assumed in most of reliability optimal allocation methods, and the fault diagnostic device is ignored in the system reliability model. In this paper, the hardware and software conditions on which the fault diagnostic device depends upon are analyzed. The fault diagnostic device is assumed imperfect and is regarded as a part of the whole system reliability model. Therefore, a more practical reliability optimal allocation method of a control system is provided. The method is used in sensors reliability optimal allocation of satellite attitude control system.
