基于PCA的故障传感器重构的理论研究
A Study on Faulty Sensor Reconstruction Based on PCA
【摘要】 本文基于 PCA(Principal componentanalysis)理论对故障传感器进行重构。首先将数据分别投影于主元子空间和残差子空间 ,然后定义故障的方向向量 ;因为过程变量间具有的强相关性 ,则沿故障各自的方向可对故障变量进行重构
【Abstract】 This paper presents faulty sensor reconstruction based on PCA. Firstly, data is projected onto principal component sub space and residual sub space respectively, then fault direction vector is defined. Due to the strong related data, fault variable can be reconstructed along its own fault direction.
