How do you do a binary search for an open-end scale (are PID params open-end?) and three knobs at the same time when they interdepend in their influence? I need to know since i have a PID tuning on my personal projects plate

It's been ages, but we'd done rough calculations for the three controls so we roughly knew what we needed. Our teacher was big on manually tuning instead of just using formulas since he thought just running numbers "lacked artfulness."

So we grabbed a point and started searching around manually. I think we were just tuning the derivative portion at that point, trying to get a fast response without the system without it going chaotic and noisy.
