Method for compensating radial error and position error of automatic rope arranging winch

The invention discloses a method for compensating radial error and position error of an automatic rope arranging winch and relates to the technical field of methods featured by compensating control devices. The method comprises following steps: calculating the relation of number of turns of a rolling cylinder to radial error and position error in advance before path interpolation of the automatic rope arranging winch; storing the series of compensation values in a rope ranging control system; compensating the rope arranging position once by the rope arranging control system through a spring compensation mechanism at a suspension center when the number of turns of the rolling cylinder changes for one time to make the winch rotate according to a space curve interpolation algorithm and compensate the rope arranging error caused by upper balance wheel position changes and rolling cylinder diameter changes of the automatic rope arranging winch. The method employs the principle of numerical control interpolation to
