Modeling methods of prognostics and health management (PHM) system, including data-based method, knowledge-based method and model-based method, are analyzed briefly. According to the characteristics of airplane, the hierarchy model of airplane PHM system , the typical module-level hydraulic pump PHM system modeling method, and experimentation validation are proposed.%简要介绍了PHM系统建模的主要方法,并依据飞机特征,给出飞机PHM系统分层体系模型,提出了基于数据的飞机典型部件液压泵PHM系统的建模方法,通过试验对该方法进行了验证.
