摘　　要：本文结合飞行器电源系统故障维护特点,利用统计过程控制理论,从数理统计的角度对电源系统测试数据进行分析,设计了电源故障预测系统。文中阐述了系统的工作原理和利用LabView软件的实现过程。实验结果表明此预测系统可以发现故障征兆及时维护,提高系统安全性。最后阐述了进一步研究可能会遇到的问题。In allusion to maintenance characters of electrical source system as an important part of aircrafts, the test data of system was analyzed by using mathematical statistics based on the theory of Statistical Process Control （SPC） and the electrical source prog- nostics system was designed in the paper. The working principle of prognostics system and working process based on LabView were described in this paper. Through experiments, it shows that the prognostics system may find fault omens to maintain in time. It can enhance safety of the whole system. Finally, some key issues to do of prognostics are listed with the goal of farther research.
