I really like that example, but I am wondering if it would really be true? Real drivers would not maintain a perfect speed, but would instead work to maintain the average. If you looked closely at the speed, it would drift away from the average, then the peddle would move to return it to the average. So it would look a bit like an integral (The I in PID control) of the difference from the mean speed right?
Yup, that's how you know I only had this on university, never used it in real life :) I think in real life you might see the feedback loop in motion, or not, depending on the resolution and sampling.
Well, we're obviously talking about perfectly spherical drivers (good point though).
Yes I figured :) Just pointing out that reality is always a bit more nuanced. To put it more simply, the petal position could be seen as an error accumulator.
