摘　　要：本发明公开了一种基于主元相似性测度的铝电解槽况诊断方法，其特征在于按如下步骤进行：一，约简原始特征：利用核主元分析法计算贡献率排在前位的m个主元B<Sub>j</Sub>；依次考察每个原始特征对表征铝电解槽况的贡献度，删掉贡献度低于贡献度阈值的原始特征，实现特征约简；二，约简后特征作为概率神经网络的输入变量，建立铝电解槽况的分类模型，模型最大输出值对应的铝电解槽况类型即为诊断结果。本发明克服了核主元无明确物理意义的缺陷，减少传感器数量和运算量，同时利用具有一次训练时间短、诊断精确度高的概率神经网络建立故障诊断模型，更加适合铝电解槽况的在线诊断。

主权项：1.一种基于主元相似性测度的铝电解槽况诊断方法，其特征在于按如下步骤进行：步骤一：约简原始特征，确定表征铝电解槽况特征的最简变量组，包括以下步骤：第一步：n个表征铝电解槽况的原始特征组成原变量组X，X=(x₁，x₂，…，x_i，…，x_n)，采集原变量组的L个样本数据，利用核主元分析法计算所述原变量组X的主元，将所有主元按贡献率由大到小排列，并计算累积贡献率，直到累积贡献率达到或超过预设的累积贡献率阈值，所累积的主元数为m，对应了所有原始特征的最少主元B_j，j=1，2，…，m；第二步：按i=1，2，…，n的顺序，依次考察原变量组X中每个变量对表征铝电解槽况的贡献度：(一)将原变量组X中的变量x_i置零，得到一个新的变量组，即待测邻点 $<math> <mrow> <mover> <mi>X</mi> <mo>~</mo> </mover> <mrow> <mo>(</mo> <mi>i</mi> <mo>)</mo> </mrow> <mo>,</mo> </mrow></math>$ $<math> <mrow> <mover> <mi>X</mi> <mo>~</mo> </mover> <mrow> <mo>(</mo> <mi>i</mi> <mo>)</mo> </mrow> <mo>=</mo> <mrow> <mo>(</mo> <msub> <mi>x</mi> <mn>1</mn> </msub> <mo>,</mo> <msub> <mi>x</mi> <mn>2</mn> </msub> <mo>,</mo> <mo>.</mo> <mo>.</mo> <mo>.</mo> <mo>,</mo> <msub> <mi>x</mi> <mrow> <mi>i</mi> <mo>-</mo> <mn>1</mn> </mrow> </msub> <mo>,</mo> <mn>0</mn> <mo>,</mo> <msub> <mi>x</mi> <mrow> <mi>i</mi> <mo>+</mo> <mn>1</mn> </mrow> </msub> <mo>,</mo> <mo>.</mo> <mo>.</mo> <mo>.</mo> <mo>,</mo> <msub> <mi>x</mi> <mi>n</mi> </msub> <mo>)</m</p><p class='subject'><strong>关键词：</strong><b class='type_ico_id'></b>铝电解槽原始特征 <b class='type_ico_id'></b>贡献度 <b class='type_ico_id'></b>概率神经网络故障诊断模型相似性测度诊断精确度分类模型 <b class='type_ico_id'></b>物理意义在线诊断诊断方法诊断结果分析法 <b class='type_ico_id'></b>贡献率运算量传感器训练 </p><p class='class'><strong>IPC专利分类号：</strong>C25C3/20(20060101)</p>
