Can anyone tell me what the difference is between a classical PID and a FLC PID? Is it just a PID where the potential is the result of applying a fuzzy-logic proposition to the inputs?
I have the same question. From their block diagram it looks like there's a PD and a PI component that get mixed together and there's a classic feedback loop with some filtering. I think the main difference is the non-linear nature of the coefficients, otherwise it has all the pieces of a traditional PID.
How does this compare to cut quality differences from things like shield gas selection, cutting speed, and laser source quality? I'd wager it's probably insignificant. Therefore, perhaps of higher use in miniature manufacturing applications than macro pieces.
I'm not familiar with laser cutting at all; are cuts typically done with suboptimal parameters for those things?
Yeah, most people have gone to using compressed air instead of shield gasses. But the point stands, how much does this vary with respect to other variables. If this is a 1% improvement where all other variables are yielding much larger swings, it may not be worth considering.
i'm interested to hear what jacquesm thinks about this
Might as well pin this to every thread.
cutting sheets of electrical steel is a subject he is especially knowledgeable about
