Modernization of a cooling water control system for the production of plastic pipes using fuzzy logic

Abstract

Fuzzy logic is successfully used in the area of control systems where different problems are decided in flexible way leading to more efficient systems' performance. Such approach is suitable when the modeled system is complex and some parameters cannot be defined precisely. In this paper a fuzzy model of improved cooling water control system utilized in plastic pipes production is proposed. Its aim is more effective regulation of the freon compressor load to be achieved that influences on economy in energy consumption. The developed model is verified through simulation in FisPro environment where the knowledge base, fuzzy membership functions and inference engine are modeled.
