A pump control assembly includes a fluid pump assembly having a fluid pump and a load sensing valve. The fluid pump includes a fluid inlet and a fluid outlet. The fluid pump includes a variable displacement mechanism. The load sensing valve is adapted to adjust the position of the variable displacement mechanism. The load sensing valve includes a first end and an oppositely disposed second end. An actuator is in fluid communication with the fluid pump assembly. A position sensor monitors the position of the actuator. A ramping valve provides selective fluid communication between the fluid outlet of the fluid pump and the first end of the load sensing valve. An electronic control unit is in electrical communication with the position sensor and the ramping valve. The electronic control unit transmits an output current to the ramping valve in response to the position of the actuator.
