Re: Neat demonstration of proportional and PID control systems

Think "D is for damping". It is kind of like software friction. It always acts in the opposite direction of motion, and is proportional to how fast the object is moving. The faster the object moves, the more the D control tries to slow it down. This helps to settle out oscillation and remove overshoot.
