" So far as the laws of
mathematics refer to reality, they are not certain. And so far as they are certain, they
do not refer to reality."
- Albert
Einstein In the mid 1960's,
the idea of white and black was challenged. In 1964 professor Lotfi Zadeh coined the
term "Fuzzy Logic." Professor Zadeh stated that there was a
"grey" area, and that not everything could be solved with only true and false
declarations. Fuzzy logic provides a way to handle things that are neither
completely true or completely false, but more somewhere in between, somewhere in
both.
A rule in the fuzzy system could look like this:
If x is fast and y is slow, then z might be zero.
This idea of vagueness provides designers a way to look at
a system and set up the control for that system. Fuzzy logic has found its way into
many modern control-systems. Below is a short list of devices that use fuzzy
logic:
-Microwaves
-Refrigerators
-Light Dimmers
-Motor Controllers
-Automobiles
-Aircraft
-Television Sets
-Stove Ovens
-OCR and OCV Systems
-Vacuum Cleaners
-Hair Dryers
-Cranes
-Electric Razors
-Camcorders
-Showers
