DC motor position drives aka servo amplifiers

I need to drive a Dc motor (24volts about 10 amps) and use it like a llarge RC servo. ie. if I tel it to go to a certain position it does so. I have one at the moment that uses a 1 to 2 msec pulse as the input (like model RC) and a potentiometer coupled to the motor shaft as feedback however I would prefer a quad encoder for feedback to help nullify the problems of varying resistance and signal noise.

Any suggestions would be appreciated.
