Design, simulation, and multiple analysis results of a stepwise improvement-based fuzzy control system to reduce shading errors occurring in the roll winding and folding processes of a carpet factory weaving unit

Abstract

Context—This study addresses the "shading” problem occurring on the surface of carpets produced in a carpet factory weaving unit. To overcome the difficulties in manually managing the parameters that trigger the "shading" problem, an expert system-based controller has been developed that can be embedded software-wise under a PLC computer and eliminates operator-induced errors in parameter management.

Objective—This study was conducted to minimize the "shading" error, observed as a chronic problem in the roll winding and folding processes, in the weaving unit of a carpet factory located in the Gaziantep Organized Industrial Zone of Türkiye. Long-term field studies using a fishbone diagram have determined that the shading observed in carpets is caused by various factors including raw material yarn thickness, environmental humidity balance, and technical machine speed. The main aim is to develop and design an AI-powered fuzzy logic quality control device that can model linguistic ambiguities based on experience.

Method—Technical investigations revealed that the problem stemmed from the nonlinear interaction between yarn thickness, ambient humidity, and machine speed. The difficulties in manually managing these variables lead to products being classified as "second quality" and significant raw material losses. Six different expert system-based fuzzy logic scenarios based on Mamdani and Sugeno were developed in the Matlab/Simulink environment to solve the problem. Based on the tests and simulations conducted, Scenario-6.1, which has the highest mathematical accuracy and compatibility with industrial systems, has been determined as the most ideal solution model.

Results—This model, structured with mixed membership functions and a rule base consisting of 100 simultaneous rules, produced the most consistent and optimized results, especially at critical production thresholds, with 56.82 quality adjustments and a speed multiplier of 1.22. In actual field testing, when risky production inputs are manually entered into the system by the operator, an approximate quality setting of 50 and a speed multiplier of 1.00 are obtained. Therefore, the value of 56.82 obtained from Scenario-6.1 shows 95% complete consistency with the parameters required to prevent errors in the factory's current quality scale, and it has increased efficiency by both improving the quality level and production speed, and very well mimicking the experience of expert operators.

Conclusion—With the integration of the developed Scenario-6.1 model into the business; uncertainties in the production process have been eliminated and the quality control mechanism has been given an autonomous structure. If the study is implemented, the aim is to achieve an improvement of over 15% in shading-related waste rates, a reduction in labor costs, and energy efficiency through the instantaneous optimization of machine speed according to yarn strength.
