Question

Describe an example of a process which would be better controlled using fuzzy logic instead of traditional binary logic. Address its advantages and identify potential drawbacks.

Answer 1

Example : Temperature control system for a Room

If we try to use simple binary logic here means set voltage control of controller and transducer that senses estemal temperature to only two levels of values 0 or 1 then we cannot get proper adjustment towards estemal room temperature variation like in case if we set 0 against temperature less than 25 ℃ and 1 for more than 25℃ .

But with fuzzy logic we can have better temperature control as we can define our own membership function that can help us to provide much more effective control , we can define our own set of input variables like very cold , cold , hot , very hot .... So that we can have much better temperature variation option for the controller !!

Advantages:

**Mathematically fuzzy reasoning is very simple and so we can modify a fuzzy system by just adding or deleting rules due to flexibility of fuzzy logic.

Drawbacks:  

**Fuzzy logic algorithms can have convergence and accuracy issues sometimes
