A system (40) for controlling a winch assembly (14) includes a rotatable winch drum (47) with an attached cable (23). A winch motor (42) is configured to rotate the winch drum. A sensor (57) is configured to generate signals indicative of the number of layers of the winch cable on the winch drum. A winch controller (51) is configured to receive a control input requesting a selected rotation of the winch drum, receive the signals from the sensor, determine a number of layers of the winch cable disposed on the winch drum, and generate control commands (71) to control the winch motor to rotate the winch drum based on the control input and the number of layers of the winch cable. The control command rotates the winch drum to produce a substantially constant line speed based on the selected control input independent of the number of layers determined to be disposed on the winch drum.
