Maybe I'm misunderstanding something, but wouldn't you still want/need a D term unless you have a system with a nearly instant response?
I'd think that even if you stop applying a delta the second you hit the set-point, if you've built up non-trivial inertia, then you'll overshoot the target fairly significantly?
