Evaluation of a pattern matching method for the Tennessee Eastman challenge process

چکیده
In this paper, we evaluate multivariate pattern matching methods for the Tennessee Eastman (TE) challenge process. The pattern matching methodology includes principal component analysis based similarity factors and dissimilarity factor of Kano et al., that compare current and historical data. In our similarity factor approach, the start and end times of disturbances are not known a priori and the data are compared by moving a window though the historical data. Comparisons with methods used in earlier case studies of the TE challenge process show advantages of using the proposed similarity factor approach. 2005 Elsevier Ltd. All rights reserved.

Fuzzy Real-Time Optimization of the Tennessee Eastman Challenge Process
A Real-Time Optimization (RTO) strategy incorporating the fuzzy sets theory is developed, where the problem constraints obtained from process considerations are treated in fuzzy environment. Furthermore, the objective function is penalized by a fuzzified form of the key process constraints. To enable using conventional optimization techniques, the resulting fuzzy optimization problem is the...
متن کاملFault diagnosis of Tennessee Eastman process using signal geometry matching technique
This article employs adaptive rank-order morphological filter to develop a pattern classification algorithm for fault diagnosis in benchmark chemical process: Tennessee Eastman process. Rank-order filtering possesses desirable properties of dealing with nonlinearities and preserving details in complex processes. Based on these benefits, the proposed algorithm achieves pattern matching through a...
متن کاملPattern recognition based on dynamic time warping and classification using adaptive rank-order morphological transform
Dynamic Time Warping (DTW) can be used to minimize distance between two sequences which display the same trends but are not perfectly aligned with each other. This feature makes DTW an effective pattern classification method for sequence matching. In Ref. [1], a fault diagnosis method using pattern classification based on adaptive rank-order morphological transform has been proposed. It uses Eu...
