Fuzzy Control Language (Paperback)

High Quality Content by WIKIPEDIA articles! Fuzzy Control Language, or FCL, is a language for implementing fuzzy logic, especially fuzzy control. It was standardized by IEC 61131-7. It is a domain-specific programming language: it has no features unrelated to fuzzy logic, so it is impossible to even print "Hello, world!." Therefore, one does not write a program in FCL, but one may write part of it in FCL.However, the programmer can simply define new sets for "very cold" and "very high." FCL also lacks support for higher-order fuzzy sets, subsets, and so on. None of these features are essential to fuzzy control, although they may be nice to have.
