Fuzzy logic and its application to textile technology
D. Veit, RWTH Aachen University, Germany
Fuzzy logic uses terms similar to human language to describe values of parameters and relations. These ‘linguistic rules’ thus allow an easy transfer of human expert knowledge onto a computer-based control system. The term ‘fuzzy’ indicates the difference to Boolean logic as not only the numbers ‘0’ and ‘1’ but also, for example, ‘0.3’ are possible. Fuzzy logic is used today in many technical devices and machines. This chapter gives an overview of the method and concludes with selected examples of successful applications of fuzzy logic to solve textile-related problems.
