Fuzzy Feedback Control for Dynamic Routing Problem

The aim of this chapter is to provide a review of fuzzy logic fundamentals for control design and then to show a design of a fuzzy feedback control law for a sample DTR problem. The fundamentals of fuzzy set theory are first presented, and then fuzzy logic is covered in terms of the fuzzy sets. Development of fuzzy control involves the concepts of fuzzification, fuzzy logic based inference engine, and defuzzification. These concepts are explained and finally a fuzzy logic based controller is designed for a routing problem and a computer simulation performed for illustration purposes.
