Both the improved PCA and conventional PCA are sued to detect the Tennessee Eastman process. The simulation results show that the two methods can detect strong changes?but the improved PCA has better performance to detect weak process changes.

• 仿真研究中,将该方法与传统的主元分析方法同时应用于TE过程中,结果表明改进主元分析方法比传统的主元分析方法(PCA)能更好的检测出对于过程影响较小的故障。
