Fuzzy Logic
Do you love Eggs?
EGGS:to wash or NOT to wash?
pretty obvious .. hehe
Where do eggs come from?
micro membrane coating
BLOOM
Tired of standing for hours washing eggs by hand?
Solution:
Fuzzy Logic
Narrow sense:
It is a logical system
Wider sense
It is synonymous to theory of fuzzy sets
4 inputs:
-
Egg dirt
-
Belt Speed
-
Water Flow rate
-
Mineral oil flow rate
3 outputs:
- Speed change
- water-valve Position change
- oil-valve Position change
How do the fuzzy controller makes "tough" decision?
by RULES..
if(audience are sleepy) then (i guess this is goodbye ;') jk
Ex. if(audience are wide awake) then ( we're good \m/)
cool :-)
easy
intuitive
english
If(this) -> then (this)
These are simple..
//Rules controlling the conveyor speed & water flow rate
1. If egg dirt is high and water flow rate is low, THEN raise water-flow rate valve slightly and don't change conveyor belt speed
2. If egg dirt is high and water flow rate is high and conveyor belt speed is high, THEN don't change water-flow rate and lower conveyor belt speed.
3. If egg dirt is low and water-flow rate is high, THEN save water by closing the valve slightly
4. If egg dirt is low and water-flow rate is low, THEN increase production by increasing conveyor speed
5. If egg dirt is acceptable, THEN don't change anything.
Fuzzy rules
//Rules controlling mineral-oil-flow rate
1. If egg dirt is extra high, THEN close the valve
//Eggs will be redirected on a conveyor back to the washers -don't waste oil
2. If the conveyor speed is high and oil-flow rate is low, THEN raise the opening valve slightly
“ If I´m not back in five minutes... just wait longer ”
Thank you!
