Is somebody working with Fuzzy Logic?

Thanks :wink:

Yes, I'm working with Fuzzy Logic? What you want?

Hi,
I have been doing bits and pieces with fuzzy logic for the past few years, mainly for students, with C code and simulation.
I am willing to help..as i am bored as hell at the moment
Regards

Can you send me some source code, then I have a look on it!

FYZZY LOGIC is very interesting area of control and electronics engineering.
there is a powerful tool named FUZZYTECH
that generates c code from block diagram.
I think it was in FILMAN.

The site confused me.
what is a good learning
program, for code output!

Re: Fuzzy Logic

I am working whit Fuzzy Logic and VHDL coke for Fuzzy Processor.

This PDF is good for start in Fozzy Logic.

Re: Fuzzy Logic

There is a book called "Design of Analog Fuzzy Logic Controllers in CMOS Techonologies" in the EDA book fourm. Currently, I am reading it and it is very interesting.

Fuzzy Logic

vhdl would take advantages, but it may uses mouts of LE

Re: Fuzzy Logic

sorry,
but what's this fuzzy logic?
why it's called fuzzy
I only know Logic
please don't be angry with me as I'm still studying electrical engineering

Re: Fuzzy Logic

in the normal logic any statement could either be true or false. in fuzzy logic any statement is true to degree and false to degree. to be more simple normal logic is black and white while fuzzy logic is a full colored. for example if we talk about tall people in normal logic we must but a clear crisp statment like " any one taller than 180 cm is tall" but what about some one 179 cm in fuzzy logic he is still tall but with a degree of say 179/180. to read more about the principles of fuzzy logic see the fuzzy system handbook by earl cox

Re: Fuzzy Logic

I question if is posible to aply normal logic add infinitum to aproximate the result? or any like is called?

You say:

if(height >= 1.80) then is tall
else not

when in fuzzy can be some like?
Code:
#define MINIMUN_STEP_FOR_FLOAT_VALUE 0.00000001f
degree=0
limit = 1.80

while(height != limit){
if( height >= limit){
degree++;
height -= MINIMUN_STEP_FOR_FLOAT_VALUE;
}else{
degree--;
height += MINIMUN_STEP_FOR_FLOAT_VALUE;
}
}
Tought the two boolean value can be used for aproximate the "degree" is that fuzzy?

Also a two bolean state can aproximate only if the number is representable, like the number PI can be aproximated in the two sides of the line with fractional numbers, but none of then will reach it ¿?

Hi Daneshgar,
