Modern control systems are mostly composed of hardware and software, the performance of which is affected by their hardware and software. Therefore, when analyzing the system's reliability, the effect of the hardware, software and their interaction must be considered. In this paper, we study the reliability analysis of the triplex electronic-hydraulic servo actuator system with a combination of FMECA and FTA. This method is partly based on the knowledge database, that is, some of the FMECA information comes from the knowledge database, and some of that comes from the analyzers. When the FMECA information of the system is enough, the subtrees of the system's typical components can be constructed with the aid of the computer, and that will help the analyzers finish the construction of the system's entire fault tree.
