“…The information increment matrix utilizes the covariance matrix of process variables to capture the dynamic characteristics of the system along the time direction. The existing information increment matrix‐based methods only concentrate on the process variables for fault diagnosis . In our article, we integrate quality‐related variables into time slices in order to emphasize the time varying relationship between the process variables and the product quality in batch processes.…”

“…However, these adaptive model methods are always time consuming when applied online, influencing the real time performance of the quality control system. A reasonable alternative method that is well suited to the process characteristic is to divide the batch process procedure into multiple phases and assign each phase a static model, which is referred to as phase‐based model methods or phase partition methods . Clustering‐based methods, the Gaussian mixture model (GMM), and the hidden Markov model (HMM) are widely used phase partition methods.…”

“…In addition, a soft transition multiple PCA (STMPCA) method is proposed by Zhao and Gao [8] and Zhang et al [9] to detect transitions between different sub-phases. Guo et al [10] introduced an innovative algorithm, namely multiway information increment matrix (MIIM), which directly extracts effective information from the covariance matrix. Moreover, the algorithm can separate the process into several different phases based on the accurate capture of variables' correlation changes.…”

“…In order to automatically identify each sub-phase according to the time sequence, a phase identification and online monitoring method based on moving window-based MIIM for the uneven batch processes (MWMIIM) is proposed in this paper, which extends the multiway information increment matrix (MIIM) algorithm to the uneven batch processes [10]. Different from the existing MIIM algorithm, the innovative points of this paper are as follows: First, phase identification of each batch is carried out separately by combining moving window technique with MIIM algorithm.…”

“…7 Recently, Cubature Kalman Filter (CKF) based on the third-degree spherical–radial cubature rule is proposed and expectations have been achieved in many applications, such as positioning, sensor data fusion and attitude estimation. 810 Afterward, cubature particle filter (CPF) is proposed based on CKF technique. Experimental results have showed that the accuracy of CPF is higher than EKPF and the precision is similar with UPF.…”
