If you think of a thermometer with a knob rather than on-off, the P adjusts the knob to get the right temperature. But it doesn't quite get it right. There has to be a difference between the actual temperature and the target temperature. That difference is what makes the heat. > The I part is: you started the turn late, you will need to spin the steering > hard now The I part is roughly, "Wait a minute. We've been close for a long time but we aren't getting there." If you integrate the error term you can get rid of it. Not in a math sense, it has an exponential tail, but eventually you get close enough for engineering. -- These are my opinions.
