A pump control system includes a source of pressurized fluid an output valve adjustably controls the flow of pressurized fluid from the source. An output valve control is coupled to the output valve and monitors the actual state of the output valve. The control selectably adjusts the output valve in response to a first control signal. A controller is coupled to the output valve control, the controller receiving information from the output valve control corresponding to the actual state of the output valve and providing to the output valve control the first control signal, the first control signal being applied to the output valve to achieve and maintain a desired state.
