ABSTRACT:
Methods and systems for controlling a hydraulic motor are described. By way of illustration, a motor control system has a first input configured to receive a step/direction command signal. A second input is configured to receive a position signal from a motor position sensor, such as a continuous turn motion sensor coupled to a hydraulic motor. A processing system is configured to control a hydraulic servo valve based at least in part on the step/direction command signal and the position signal.
