Fuzzy Logic
Applications
-
-
-
Prediction, diagnostic and advisory systems
-

Introduction
-
"degrees of truth" rather than the usual "true or false" (1 or 0) Boolean on which modern computer is based on
-
-
-
-
-
Fills gap in engineering design methods which is based on purely mathematical e.g. linear control design and logic-based approaches e.g. expert systems.
Algorithm
- Define linguistic variable and terms
-
- Construct membership functions for them
-
- Construct knowledge base of rules
-
- Obtain fuzzy value (Fuzzification)
-
-
- Evaluate rules in the rule base (Inference engine)
- Combine results from each rule (Inference engine)
Advantages
Easy to understand, flexible and tolerant of imprecise data
