  2. Sure. Integrators make the error zero. As does an
    infinitely high proportional part. If the acceptable
    error a bit above zero, the proportional part may
    be a bit below infinte.

  3. Certainly. Furthermore, the servo can be controlled not just without I,
    but without P,I and D altogether.
    So what?

  4. I think that you meant : an integrator in the forward path makes the static
    error zero.

  5. Maybe.
