A hydraulic control system is provided for regulating the slew rate of a servovalve driven actuator within design parameters despite widely varying load conditions. The servovale flow is maintained constant in accord with the integration of the difference between a set slew rate command signal and a measured slew rate feedback signal. Where a plurality of such actuators are driven from a single hydraulic pump, this regulation of servovalve flow also enables the pump supply pressure to remain constant despite widely varying load conditions on the individual actuators in the system.
