I assume they use a subroutine that used to be called fuzzy logic, which allows them to learn from their situation and make appropriate adjustments as conditions change. ~ wirestripper

No, you have your terminology mixed up. You are most likely referring to a type of control system called a "feedback control loop". Fuzzy logic, unlike binary logic, which has only 2 states for the flip-flop (on or off), will have transistors that have 3 or more discrete states.

Though fuzzy logic systems have their place today, I doubt that the shuttle computers use them. If my memory serves me, the shuttle employs an 8088 type of processor that Intel put into computers before the advent of the 286 computers. Though, they could have upgraded the computer systems making my knowledge obselete.

Thanks Woody!

I have been out of the loop, so to speak, on processor control since my days with Allen Bradley and Honeywell.

I am sure the new stuff is much better than the old days.
