Abstract

本发明涉及航空液压系统健康管理技术领域，公开了一种基于数据驱动的机载液压系统流量预测方法，通过对机载液压系统特征参数集中的数据进行探索，选择合适的流量预测建模算法进行模型训练得到液压系统流量预测模型；然后进行模型评估，选择符合指标要求的液压系统流量预测模型进行可解释性分析；其中模型可解释性分析流程通过模型判断、全局方法、局部方法、模型可解释性判断步骤判断该流量预测模型的预测过程是否与系统运行机理相符，若不相符则重新进入模型建立流程，直至得到与液压系统运行机理相符且流量预测准确度满足要求的液压系统流量预测模型，为高准确度的流量预测模型在航空液压系统健康管理的实际应用和部署提供有利条件。
