Thats actually a pretty cool learning experience!

If I am understanding you correctly, you were essentially integrating the output of a PD controller, which would effectively give you a PI controller?

Integrated once, P becomes I, D becomes P, so PD = IP = PI?

I'm wondering if there are any useful side effects to this method... I'll ponder it more when I'm not on drugs (lousy cold!)
