Apparatuses and methods for controlling the slip of a work machine having a ground-engaging traction device and a hitch operable to receive a ground-engaging implement. A control system receives an actual velocity signal indicative of an actual velocity of the work machine, an apparent velocity signal indicative of an apparent velocity of the work machine, and a desired slip signal indicative of a desired slip of the work machine. The control system determines an actual derivative of slip of the work machine as a function of the actual velocity signal and the apparent velocity signal, and transmits a control signal as a function of the desired slip signal, the actual velocity signal, the apparent velocity signal, and the actual derivative of the slip. The control signal controls the vertical position of one of the hitch and the ground-engaging implement.
