Muguang Zhang, Auteur ; Zhiqiang Ge, Auteur ; Zhihuan Song, Auteur |In this paper, a new fault detection and identification scheme that is based on the global―Iocal structure analysis (GLSA) model is proposed. By exploiting the underlying geometrical manifold and simultaneously keeping the global data informatio[...]

Zhiqiang Ge, Auteur ; Zhihuan Song, Auteur |For probabilistic monitoring of nonlinear processes, the traditional probabilistic principal component analysis (PPCA)-based monitoring method is generalized through the kernel method. Thus, a probabilistic kernel PCA method is proposed for proc[...]

Zhiqiang Ge, Auteur ; Lei Xie, Auteur |Conventional methods are under the assumption that a process is driven by either non-Gaussian or Gaussian essential variables. However, many complex processes may be simultaneously driven by these two types of essential source. This paper propos[...]

Zhiqiang Ge, Auteur ; Chunjie Yang, Auteur ; Zhihuan Song, Auteur |A robust online monitoring approach based on nonlinear external analysis is proposed for monitoring multimode processes. External analysis was previously proposed to distinguish faults from normal changes in operating conditions. However, linear[...]

Zhiqiang Ge, Auteur ; Zhihuan Song, Auteur ; Furong Gao, Auteur |This paper develops a modeling approach to address the end-of-batch product quality prediction problem for batch processes with limited batch-cycle data. Generally, those batch processes that have multiple phases are the focus of the present pap[...]
