Yay someone else who went through controls nonsense! Actually, it's funny how you explained the PID control used in most control logic feedback loops....because you'd think you'd never really get the chance to use that kind of knowledge sitting through the class and exams but alas, here we are talking about electronic boost control, of which most people couldn't care less about how it works, but without all the complicated, behind-the-scenes logic using calculus, there would be no fine tuning of boost.

Good explanation Jspaeth....where'd you finish your undergrad? I guess we could also argue that using a block diagram and modeling the ICE and turbocharger and with some assumptions, calculate the precise numbers to manipulate how the boost controller performs. I'll task you with that portion since you chimed in on PID control haha.
