摘要:讨论了基于主元分析 ( PCA)的过程故障检测与诊断的原理 ,运用 T2统计、Q统计方法 ,结合贡献图对一典型过程进行了仿真分析 ,结果表明 PCA方法可对简单传感器故障进行检测与诊断 ,并指出了该方法中的不足 ,提出了将
Fault detection and diagnosis method based on the principal components analysis (PCA) is discussed . The fault detection and diagnosis simulation to a typical chemical process is performed by means of statistical methods like Holleting T 2 and Q. The contribution charts are used to undertake fault diagnosis. The simulation results show that PCA is an effective approach to fault detection and can only work for the simple sensor fault diagnosis. A novel idea to combine PCA with causal model based approach...
