A Fuzzy Control system is a control system based on fuzzy logic a mathematical system that analyzes analog input values in
terms of logical variables that take on continuous values between 0 and 1, in
contrast to classical or digital logic, which operates on discrete values of
either One or Zero i-e (true or false)
Fuzzification
The
Fuzzification comprises the process of transforming crisp values into grades of
membership for linguistic terms of fuzzy sets OR
Modifies inputs so that rule base can be interpreted and compared in rule base.
The membership function is used to associate a grade to each linguistic term
such as
NEGATIVE
LARGE (NL), NEGATIVE MEDIUM (NM), ZERO, POSITIVE MEDIUM (PM), POSITIVE LARGE
(PL)
Defuzzification:
Converts the
conclusion to crisp input for the controller.
