摘　　要：针对现有在轨卫星故障诊断方法不足的问题,提出了一种基于Clips专家系统的卫星故障诊断系统。该系统利用已有的卫星故障知识和经验,将专家经验和实时遥测数据相结合,采用推理机技术实时诊断卫星故障,同时通过可视化技术包括图形化和知识表达式两种方式进行专家知识录入编辑,构建专家知识库从而将用户容易理解的简单的逻辑语句转化为完整的复杂的Clips语句实现复杂的故障诊断程序,进而实现在轨航天器实时故障诊断的自动化和智能化,精准定位故障,提高卫星系统的可靠性和安全性。经模拟多种故障场景以及项目实践多方验证,卫星故障诊断系统的诊断结果与卫星实际接收的故障数据相同,证实了设计系统的有效性。Aiming at the shortage of existing fault diagnosis methods for in-orbit satellites,a satellite fault diagnosis system based on Clips expert system is proposed in this paper.The satellite fault is diag-nosed in real time by taking advantage of existing satellite fault knowledge and experience,combining expert experience with real-time telemetry data and using inference machine technology.At the same time,expert knowledge is input and edited by visualization technology including graphics and knowledge expression.The expert knowledge base is established to transform the simple logic statements that is easy to be understood by users into complete and complex Clips statements to realize complex fault diagnosis programs,and it is going on to realize the automation and intelligence of real-time fault diagnosis of spacecraft in orbit,accurately locate faults and improve the reliability and safety of satellite systems.Through multi-domain simulation of multiple fault scenarios and project practice,the diagnosis results of the satellite fault diagnosis system are the same as the actual fault data received by the satellite,which verifies the effectiveness of the designed system.
