PID is the controller for a block diagram [1]. When you have the block diagram, you can predict the response graphs extremely reliably [2]. You should be extremely close to the desired coefficients and requires a little tuning. Especially for stuff like thermal and conduction that’s very well understood. You just need to draw the thermal circuit and know the spec of your hardware. Most of the time people use PID, they use it as a black box which causes a lot of pain.
