Controlling method of ship cable winch driving system

The invention discloses a controlling method of a ship cable winch driving system. The controlling method is used for improving the dynamic and static performances of a ship cable winch. According to the technical scheme disclosed by the invention, the controlling method utilizes a variable universe fuzzy controller to regulate control parameters of a PI controller by adopting a fuzzy reasoning method when controlling the ship cable winch by utilizing the PI controller, so that double closed-loop adaptive control of a rotational speed and a current of the ship cable winch driving system is realized, wherein the variable universe fuzzy controller takes a torque error E and a torque error change rate EC as input and corrected delta Kp and delta Ki of two parameters P and I of the PI controller as output. The controlling method realizes double closed-loop adaptive control of the rotational speed and the current of the ship cable winch driving system, effectively improves the controlling accuracy of the ship cabl
