| Abstract: | In this paper, a nonlinear PCA (principal component analysis) method for fault detection based on input-train neural network (IT-net) is proposed for the reason that linear PCA method is difficult to capture nonlinear statistical characteristic information. Design scheme of process perform monitoring system based on the algorithm and its application to batch processes are discussed. The algorithm validity is demonstrated by simulation results. |
