针对飞机四余度舵机系统高可靠性和维修保障性要求,根据系统故障特点,提出了预测与健康管理系统的体系结构总体方案,描述了各层的功能,并对机载四余度舵机健康监测系统和地面健康管理系统关键技术进行了研究,基于信标的多任务异常分析技术,给出了时序、解释和神经网络等故障诊断算法,最后对预测与健康管理系统的三大工程集成环境做了介绍,为系统故障预测和后勤保障提供了工程方法。
According to the requirements of high reliability and maintenance of aircraft four-servo system, according to the characteristics of system failure, the overall scheme of the system of prediction and health management system is proposed, the functions of each layer are described, Machine health monitoring system and ground health management system. Based on the beacon multi-task anomaly analysis technology, fault diagnosis algorithms such as timing, interpretation and neural network are given. Finally, the three major projects of forecasting and health management system are integrated The environment was introduced, providing engineering methods for system fault prediction and logistical support.
