摘　　要：粗糙集理论是一种处理模糊和不确定性知识的较新的数学工具,将粗糙集理论引入到异步电动机故障诊断中,对电机的运行状态决策表进行属性约简,有效提取重要属性,降低决策表的冗余性。分析表明,粗糙集理论应用于交流异步电动机故障诊断可得到更清晰、简明的诊断规则。Rough set theory is a new mathematical tool to deal with deals with fault diagnosis of asynchronous motor, deals with the attribute cision-making table of the asynchronous motor is utilized. The important vagueness and uncertainty. The theory to reduction for the operational condition de- attributes were extracted so as to decrease redundancy of a decision-making table. The analysis shows that more clear and concise diagnostic rules could be acquired by using rough set theory.
