A velocity form PID algorithm provides a clear advantage for these types of control schemes. Since the previous output of the loop is available in the CVn-1 term, it is a simple matter of wiring the output Inertia processes a bodies velocity derived from its previous position. It is easy to see why this relatively simple scheme does not preserve impulse energy.The verlet constraint resolution just moves the bodies around in order to be conflict free, and the velocity is encoded in the previous position, which is not adjusted for impulse preservation.
