Abstract
An automatic drilling system is disclosed which includes an electric servo motor operatively coupled to a winch brake control, a servo controller operatively coupled to the servo motor, and a drum position encoder rotationally coupled to a winch drum. The controller is adapted to operate the servo motor in response to measurements of position made by the encoder so that a selected rate of rotation of the drum is maintained.
