液压系统故障检测与诊断技术的新进展

New Reserach Developments on Hydraulic System Fault Detection and Diagnostics

阐述液压系统故障检测与诊断技术的研究现状，指出现有各种单一诊断方法存在的缺陷，论述解析冗余与ＡＮＮ融合，小波分析、模糊逻辑与ＡＮＮ融合以及ＥＳ与ＡＩ融合的诊断方法是克服单一诊断方法缺陷的有效途径，并对今后的发展方向进行展望。

This paper elaborates the recent research developments on the hydraulic system fault detection and diagnosis technique,and points out the shortcomings existing in the available single diagnosis method.The diagnosis methods fusing analytic redundancy and ANN,the diagnosis methods fusing wavelet analysis,ANN and fuzzy logic,the diagnosis methods fusing ES and ANN are the effective ways for overcoming these defects.Moreover,the paper looks forward to the future research trends in this field.
