Question

Defuzzification in fuzzy control refers to

• A. Fuzzifying inputs
• B. Rule evaluation
• C. Converting fuzzy output to crisp value
• D. Error computation

Hint:

Stages of a fuzzy controller: \[ \boxed{ \text{Input} \rightarrow \text{Fuzzification} \rightarrow \text{Inference} \rightarrow \text{Defuzzification} \rightarrow \text{Crisp Output} } \]

Answer 1

The Correct Option is C

Step 1: Recall the stages of a fuzzy logic controller. The basic stages are: \[ \text{Fuzzification} \rightarrow \text{Inference (Rule Evaluation)} \rightarrow \text{Defuzzification}. \]

Step 2: Define defuzzification. Defuzzification converts the fuzzy output obtained after inference into a single numerical (crisp) value. Thus, \[ \boxed{\text{Converting fuzzy output to a crisp value}} \] is the correct answer. Therefore, \[ \boxed{(C)} \] is the correct answer.
