Fuzzy logic has been used in a variety of widely varying applications. Its most visible use is in control systems where fuzzy systems have had commercial success. Fuzzy logic has also been applied to self-focusing cameras , cement mixing systems, vehicle controls including anti-lock breaking systems, and even rules-based systems.
Probably the most successful applications are the ones that remain unknown. The name fuzzy logic itself doesn't promote a sense of reliability, though technically we know it is a sound method. As with many other AI methods , there exists a slow migration into the practical realm where someday fuzzy logic will not be associated with AI but instead seen as a visible standard technical solution.
