| 摘 要： | 给出了故障诊断系统的性能评估指标体系的选取原则;建立了故障诊断系统性能评估的指标体系,将故障诊断系统的性能指标归结为3大类指标:检测性能指标、诊断性能指标、综合性能指标;结合故障检测滤波器方法、基于粗集模型故障诊断方法和基于粗糙神经网络故障诊断方法进行了具体的评估,评估中各指标的权重采用两两比较法进行确定,所得的综合评估结果与实际情况相符。

| Abstract: | The principle for selecting performance evaluation index of the fault diagnosis system is given. The performance evaluation index system of the fault diagnosis system is established. The performance indices are classified into the detection performance index, the diagnosis performance index and the comprehensive performance index. Some practical fault diagnosis methods, such as the fault detection filter method, the fault diagnosis method based on rough set modal and the fault diagnosis method based on rough neural network are evaluated. A number of valuable conclusions are obtained. |
