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 ; Zhihuan Song, Auteur |This paper proposes an effective nonlinear soft sensor based on relevance vector machine (RVM), which was originally proposed in the machine learning area. Compared to the widely used support vector machine (SVM) and least-squares support vector[...]

Hong Wang, Auteur ; Tore Hagglund, Auteur ; Zhihuan Song, Auteur |There is normally a mismatch between the current model of the plant and the model that was used for design. This mismatch is normally acceptable when the controller is designed. But if the process dynamics changes, the mismatch may be so large t[...]

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[...]

Zhibo Zhu, Auteur ; Zhihuan Song, Auteur ; Palazoglu Ahmet, Auteur |Monitoring and management of process transitions is a critical activity in chemical plants due to increased potential for abnormal operations. This activity is often hampered by the lack of a proper approach to label the transition states. In th[...]
