Abstract
A number of steps are involved in manufacturing process of an insulated wire. One of the most significant steps of all is controlling the temperature of the poly vinyl chloride (PVC) material which we are going to control using fuzzy logic. The required temperature is set in accordance to the grade of the PVC material available, with no need of manual surveillance. The purpose of this paper is to implement fuzzy logic in wire manufacturing and thus make it autonomous. Keywords: Fuzzy logic, PVC, PVC extruder, fuzzification, defuzzification.
Highlights
The wire and poly vinyl chloride (PVC) material undergoes several steps before insulated wire is manufactured
The oven is used for drying process and the temperature control is often done by manually. This imposes the greatest problem as the slightest negligence can result in the burning out of the PVC material changing its colour and making it useless
After the moisture is driven out, the PVC material is fed into extruder machine
Summary
The wire and PVC material undergoes several steps before insulated wire is manufactured. According to the grade our fuzzy based system sets the temperature to drive out the moisture content through oven. Fuzzy inference scheme-I (FIS-I) The fuzzy based system designed will set the temperature to make the PVC material moisture free. We have decided to give total of 20 points to five different grades and use fuzzy logic to remove the ambiguity prevailed in the classification due to lack of distinct category. The grade point is our input and is going to determine the set temperature for the removal of moisture from the PVC raw material. According to the grade of raw PVC material, fuzzy based system decides the set point temperature of PVC. After taking an input point grade from the operator, the following rules are processed in FIS-I The fuzzy module for FIS-I is shown Table 1.
