【摘要】 对基于自回归模型机组振动状态时序识别系统常用的5种判别函数的判别性能,从理论上进行了定性分析,同时定量地比较了它们对试验摩擦振动状态的分类概率。指出了这5种判别函数各自的特点,对它们分类能力进行了评价。其评价结果为选择机组振动状态时序识别系统的判别函数提供了依据。更多还原

【Abstract】 The paper qualitatively analyzes five common discriminate functions of turbogenerator vibration state time series identification system based on AR model. The paper also compares their classification probabilities to experiment rub vibration states quantitatively. The paper gives out their features and evaluates their classification quality. These results provide a base for choosing proper discriminate function of turbogenerator vibration state time series identification system.更多还原
