Just watched, and yes this is a very good explanation. My intro to PID controllers was when writing AI vehicle steering for video games. I wasn’t taught about PID controllers in my CS degrees, so I started naively with what I would later learn is a P controller, and then got really surprised when lowering the gain turned into larger error. Like trying to smooth out the steering makes the problem worse, it was surprising to me. I told a very smart guy near me what I’d learned and he was like, “Oh yeah, you just need a PID controller”.
