基于变量分组DTW-MCVA的不等长间歇过程故障检测方法
Fault detection method of unequal-length batch process based on VGDTW-MCVA
摘要
Abstract
Aiming at the problem that batch data synchronization in unequal-length batch process monitoring fails to fully exploit local information, this paper proposes a variable grouping dynamic time warping-multiway canonical variate analysis (VGDTW-CVA) algorithm for unequal-length batch process fault detection. First, the mutual information matrix is used to describe the correlation between variables of unequal-length batch process, and all the variables are divided into serval groups based on mutual information matrix. Then use the DTW algorithm to synchronize each variable group separately, and integrate the synchronized variable groups into a complete 3D data set. Finally, MCVA method is utilized to establish dynamic monitoring model for online monitoring of batch production process. The simulation results on the penicillin simulation system show that the VGDTW-MCVA has better monitoring effect for the unequal-length batch production process.关键词
