A hydraulic control system having a pump for delivering fluid under pressure from a fluid reservoir, a hydraulic actuator selectively driven by the fluid, the system comprises a main flow control valve connected between the pump and the actuator for selectively providing the fluid to and from the actuator, and a control unit connected to the main flow control valve for controlling operation of the main flow control valve to control the rate of change of the area of the main flow control valve relative to the delivery of fluid from the pump, and the control unit connected to the pump to increase or decrease the actual pump command proportional to the inverse of the pump command.

1. A hydraulic control system having a pump for delivering fluid under pressure from a fluid reservoir, a hydraulic actuator selectively driven by the fluid, the system comprising:a main flow control valve connected between the pump and the actuator for selectively providing the fluid to and from the actuator; and a control unit connected to the main flow control valve for controlling operation of the main flow control valve to limit the rate of change of the area of the main flow control valve dependent on the rate of delivery of fluid from the pump.
