Abstract :
The main goal of the study is to introduce two fuzzy control systems for traffic signal control. Two different fuzzy control methods are tested in both control systems and their mutual goodness is compared. The tested fuzzy inference methods are a traditional Mamdani-type system and a fuzzy inference method based on maximal fuzzy similarity. For the fuzzy inference method based on maximal fuzzy similarity there is introduced an extension for which fuzzy inference systems where both input and output spaces are fuzzy can be constructed. The second goal of this study is to introduce a method for stability analysis of fuzzy control systems, fuzzy rulebase and membership functions
