Fail-safe design based on fta

摘要

Fail-safe design is an important technique in the design of system safety, and Fault tree anaysis is a very important system reliability & safety analysis method. This paper introduces fail-safe firstly, then shows the procedure of fail-safe deisgn based on FTA and the rules and methods to identify the key components i nthe fail-safe design, finally gives a particular fail-safe design example about satellite rotate speed control system.
