56369 航天继电器作为液体运载火箭等大型结构件复杂电子系统中的关键部件之一,其工作状态直接决定整个系统能否正常工作. The aerospace relay is an important part of the complex electronic systems in large-scale structuralcomponents, such as the launch vehicle, and its working state determines whether the system can work properly.
56370 本文针对航天继电器使用过程中所面临的高价值样本缺乏、系统复杂、复杂环境干扰等难题,基于考虑属性可靠度的置信规则库(belief rule base with attribute reliability,BRB-r)专家系统提出了一种新的考虑环境干扰的航天继电器故障诊断与容错控制框架. Due to the lack of high-value samples, the complexity of the system, and the multiple environment disturbancefactors affecting the aerospace relay, in this study, we developed a new fault diagnosis and tolerance controlframework for the aerospace relay based on a belief rule base with attribute reliability (BRB-r).
56371 在所提出的新框架中,对航天继电器输出监测指标进行分析,基于BRB-r建立航天继电器故障诊断模型,通过其工作状态评估结果,分为功能正常、功能缺陷和功能丧失3种; In the proposedframework, to develop a fault diagnosis model based on BRB-r for the aerospace relay, we analyze the monitoringcharacteristics and divide the working state of the relay into categories: normal function, defective function, andloss of function.
56372 然后,针对3种状态分别设计3种控制策略:保持原控制输入、重构控制率和切换备份继电器. Then, we provide three respective control strategies for these three working states: maintain theoriginal control input, reconfigure the control rate, and switch the relay.
56373 本文所提方法通过实验室所搭建的JRC-7M航天继电器测试系统进行了实验验证. We demonstrated the performance of theproposed model in an experiment using the JRC-7M aerospace relay based on the test system in the laboratory.
56374 针对复杂战场环境下确定无人机安全飞行区域的过程中面对的复杂性和不确定性问题,本文提出了一种基于变权理论和马尔可夫模型的无人机安全飞行区域确定方法. To manage the complexity and uncertainty faced by an unmanned aerial vehicle (UAV) and identifya safe flight area in a battlefield environment, we propose a method for determining the safe flight area of theUAV based on the variable weight theory and a Markov model.
56375 根据无人机相对于威胁区域距离的不同,引入变权理论对威胁指标权值进行调整,完成综合威胁大小计算. In the threat calculation, the variable weighttheory is introduced, so that the weight can be adjusted according to the position of the UAV relative to thethreat area.
56376 然后,利用马尔可夫模型对无人机飞行过程中受到的潜在威胁进行预测. Then, the Markov model is used to predict the environmental threat the UAV may encounter duringits flight.
56377 接着,使用模糊评估方法评估无人机飞行区域的威胁等级,并引入云模型构建隶属度函数,以提高评估结果的可靠性. Then, a fuzzy evaluation method is used to determine the threat level in the UAV flight area, and acloud model is introduced to construct a membership function that improves the reliability of the result.
