摘要
故障预测是实现视情维修策略的基础.不确定性问题在故障预测中普遍存在,对此,总结了基于不确定性的故障预测方法的关键问题,并以不确定性属性的特点将现有故障预测方法分为基于随机性、模糊性、灰性及混合不确定性等4类.综述了各类方法的研究现状与不足,并展望了基于不确定性的故障预测方法的发展趋势,探讨了基于区间不确定性的故障预测方法的可行性.
Fault prognosis is the fundamental of realizing condition based maintenance. Uncertain problems exist in the general process of fault prognosis. Therefore, the key issues of fault prognosis based on uncertainty are summarized. Then existing fault prognostic methods are categorized into four types, i.e. methods based on randomness, fuzziness, grey property and integrated property. A review is made on the current research status and shortcomings of the main methods. The development trends of fault prognostic methods based on uncertainty are indicated, and the feasibility of possible fault prognostic methods based on interval uncertainty is discussed.
