Fuzzy Logic: Fundamentals and Applications

Fuzzy logic is an applied branch of Mathematics having numerous applications across diverse fields. This paper presents an introduction to the fundamentals of fuzzy logic and explores its various applications in real life. The concept of fuzzy logic is based on human thinking and natural behaviour. This theory replicates human psychology in terms of how people make decisions quickly and with imprecise information. Unlike traditional binary logic, which only uses two values-0 (for false) and 1 (for true), fuzzy logic describes human reasoning by using the entire range between 0 and 1 . It interacts with incoming data in a more human-like manner, using an imprecise yet highly descriptive language. It can be implemented through hardware, software, or a combination of both. As a bridge between human thought and computational systems, fuzzy logic improves communications and understanding between humans and machines. Its flexibility and performance have made it among the preferred solutions for numerous control system applications.
