A lack of demonstrable benefits would be at the top of my list.Analog said:As I recall, it was quite the buzz about 10-15 years ago. Haven't heard much about it in recent times.
Anyone use it, or know why it has faded from the EE front pages?

Anything which learns your preferences or previous settings could be said to be exhibiting fuzzy logic.

Pommie said:If that is true then I hate fuzzy logic. I want my car, computer, phone etc to be exactly the same every time I use them unless I change them. My current car has DAT (driver assist technology), it basically changes down gear if you touch the brake while going down hill. Drives me mad, it's like having someone in the back playing with the gearbox. Also, if I pull out of a junction and stick my foot down, it decides I'm a boy racer and keeps the engine in the power band for the next 20 seconds or so making the ride very jerky. Toyota assure me that this is working as designed.
When I first installed XP, it had that stupid "keep things that you used last on the menu" system enabled. It just meant that I had to read the menu every time to find out where the item I wanted was. I eventually worked out how to turn it off.
I used to be able to hover my mouse over the clock in the corner and it displayed the date, now it doesn't do that any more. I guess that was a security update.</rant>

Sceadwian said:Fuzzy logic is a buzz word based on the so called fuzzy set theory in mathematics. All PID loops are effectively fuzzy logic routines, nobody calls them that. It's basically a digital quantization of the analog world, the more bits you use the 'fuzzier' it is. There's black and white, and then there's fuzzy which is shades of gray. I've been looking at gray scale images for years without calling them fuzzy logic based image representation methodologies =)
It could just as easily be called quantized analog logic, or complex hysteresis based value engineering, or some other equally long winded smart sounding snuff.
Another problem faced with PID controllers is that they are linear. Thus performance of PID controllers in non-linear systems (such as HVAC systems) is variable. Often PID controllers are enhanced through methods such as scheduling or fuzzy logic.
Nigel Goodwin said:Shouldn't have a silly automatic gearbox then!Right On, Nigel. Full control and full satisfaction comes from a pedal and a lever attached to a dry clutch manually operated transmission. (haven't tried an SMG type, but seems like blasphemy to me). I'll save further thoughts for automobile bulletin boards.
