| Abstract: | 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. |
