1. A system for controlling a function of a machine system comprising an off-road work vehicle, a moveable device adapted to perform the function and a positioning assembly coupled to the vehicle and including an actuator for moving the moveable device in response to a control signal, the control system comprising:

  • an operator-adjustable input device configured to generate an input signal; and

    a control circuit coupled to the input device and the actuator, the control circuit configured to determine a rate of change of the input signal and to generate the control signal for moving the moveable device in either a first manner or a second manner depending upon the rate of change of the input signal;

    wherein the control circuit is configured to generate the control signal in the first manner when the rate of change of the input signal is less than a threshold value and in the second manner when the rate of change exceeds the threshold value;

    wherein, when operating in the first manner, the control circuit is configured to generate the control signal such that the rate of movement of the actuator is slower than the rate of movement would have been if the control circuit was operating in the second manner.
