The invention discloses a control method, a control system and a controller of a super-lift mast. The method comprises the following steps: acquiring a linear velocity relationship between a main variable-amplitude hoisting steel wire rope and a superlift variable-amplitude hoisting steel wire rope; determining an initial main variable amplitude winch control current and an initial superlift variable amplitude winch control current according to the linear velocity relationship; controlling a main variable amplitude winch to move according to the initial main variable amplitude winch control current, and controlling a superlift variable amplitude winch to move according to the initial superlift variable amplitude winch control current; the pulling force of the super-lift mast is obtained in real time in the movement process of the super-lift variable-amplitude winch; and the main variable amplitude winch control current and the superlift variable amplitude winch control current are adjusted according to the pulling force of the superlift mast until the superlift mast moves to the target position. The motion of the main variable amplitude winch and the motion of the super-lift variable amplitude winch are controlled through the main variable amplitude winch control current and the super-lift variable amplitude winch control current, the operation difficulty in the rising and falling process of the super-lift mast is reduced, and the operation precision and efficiency are improved.
