yup. i get it. it's a steep learning curve. and it's hard to grok if you don't understand what the theory behind them is.

My bigger point is that the articles like the one linked here just barely scratch the surface and you cannot really jump into it and get an intuitive understanding by just looking at it. that being said, if you want to learn more you can and they can be applied to a large range of problems.

Control theorist here. The articles are pretty good. There is nothing wrong with them.

What you are insinuating is not always correct that if you model stuff you'll get a better result. Sometimes PID is more then enough and in fact better since your model can get arbitrarily complex and you don't have any tools to deal with that behavior. It's a bit snobbish that you need to have math and all the shenanigans. The rest of the manufacturing world disagrees with your premise that is very common in academic circles.

Maybe you need a controller for how you interact over here?

Nobody was insinuating anything. I was pointing out that going past an intuitive understanding may be a harder leap than expected.

How about you don't kick off with a lol then? Maybe you set the tone of engagement.

Agree. That's what I get for not having a D element on the direct path :)
