Yes, that's understood. But let's take just a simple P controller. Having
its output going towards the motor voltage (like through PWM control) makes
this P controller actually an I controller WRT position -- the motor
movement provides the integration WRT position. So why have an I part in
the controller? The way I understand it, a PD controller position
controller would act in effect as a PI controller (the D part becomes the P
part, and the P part becomes the I part), because of the integration
through the motor movement.

Or is this way off?
