摘要
结合飞行器电源系统组成,以单机部组件作为最低约定层次,明确了各层级故障诊断系统功能,基于电源系统特征提出观测点选择与配置过程和一般原则,并应用TMAS软件完成系统测试性建模设计,建立电源系统参数与故障相关性模型,仿真结果表明观测点设置合理,故障检测率满足任务要求,为后续开展飞行器电源系统故障诊断及管理研究提供基础。
The functions and components of fault diagnosis system were introduced by combining the aircraft power system structure. Basing on the characters of the system, the processes and principles on selection and configuration of observation points were proposed. Using the TMAS software, the testability model was designed,and the correlation model with the parameters and faults of the power system was built. The simulation results show that, the configuration of observation points is available and the fault detection rate satisfies the mission requirements.
