Abstract
The present disclosure relates to a method for controlling the orientation of a crane load, wherein a manipulator for manipulating the load is connected by a rotator unit to a hook suspended on ropes and the skew angle ηL of the load is controlled by a control unit of the crane, characterized in that the control unit is an adaptive control unit wherein an estimated system state of the crane system is determined by use of a nonlinear model describing the skew dynamics during operation.
