Application of Rough Set Theory in Fault Diagnosis of Hydraulic Pump
Author(s): 
Pages: 20-22
Year: Issue:  4
Journal: HYDRAULICS PNEUMATICS & SEALS

Keyword:  粗糙集阶比分析液压泵故障诊断;
Abstract: 针对液压泵故障诊断特性参数多、故障诊断模糊性强的特点,提出应用阶比分析方法消除与振动信号无关的噪声干扰,然后利用粗糙集理论对故障诊断决策表进行约简,获得最优决策系统,最后在最优决策系统的基础上,形成液压泵故障诊断规则,有效提高了液压泵故障诊断的精度和效率.
