Quality Evaluation Based Fuzzy Residual Modelling. Application in Hot Rolling

Abstract:- On line quality evaluation is an important domain particularly in the complex processes where the characteristic of the product quality is difficult to measure directly. Evaluation based modelling techniques can be considered as an alternative to solve such complex problem. We consider in this work a contribution for product quality evaluation in hot rolling using fuzzy models. Residual changes are used to obtain an evaluation of product quality. Fuzzy rules are implemented in basis of the residual and first derivative changes. Application in hot rolling shows that this approach can be recommended as part of a tool of on line quality evaluation and classification
