基于变精度粗糙集的柴油发电机排气阀故障诊断方法研究

Study on fault diagnosis for diesel engine exhaust valve based on variable precision rough sets model

提出一种基于变精度粗糙集算法的阀门故障诊断方法。该方法具有一定的容错能力,同时能够在确保故障规则具有较高准确度和覆盖度的前提下得到尽可能简洁的规则集。将该方法用于柴油机排气阀典型故障的诊断,研究表明该方法具有良好的故障诊断性能。

A Valve fault diagnosis method based on Variable Precision Rough Sets Model（VPRSM）is proposed.The fault-tolerant ability of VPRSM can get compact,veracity and inclusive rule.Using the method,some faults of Diesel Engine Exhaust Valve have been diagnosed correctly.The result shows that this method can differentiate the faults of the Valve rapidly and accurately.
