摘要：
Aero-engine control system is a key system in aircraft. Its testing and maintenance rely more and more on effective work of built-in test (BIT) subsystem. However, BIT subsystem suffers false alarm all the time. BIT subsystem and its influence on the reliability of aero-engine control system are introduced first in this paper. Then the cause of false alarm in BIT subsystem is analyzed and measures of reducing false alarm are proposed. Finally, it takes MBIT of power converter in starter/generator, for example, to verify the proposed measures. The theoretical result has significance in promoting wide application of BIT technology.
