Abstract

This paper presents a control system that reduces pendulation of suspended loads in offshore lifting operations. The kinematic model of the ship and crane together with the designed anti-pendulation ami are presented. Linear control design techniques for the linearised model are proposed aiming at controlling pendulation in the presence of sea disturbances. These techniques involve LGQ and Generalised predictive control. The use of a dynamic model for the vessel dynamics and the sea wave disturbances in the control design improve the behaviour of the controlled system. Finally simulation results and comparisons are given.
