关于自适应反步控制的双螺旋桨自动靠泊文献，最新的-The auto-berthing of a ship requires excellent control for safe accomplishment. Crabbing, which is the

pure sway motion of a ship without surge velocity, can be used for this purpose. Crabbing is induced by a peculiar

operation procedure known as the push-pull mode. When a ship is in the push-pull mode, an interacting force is induced

by complex turbulent flow around the ship generated by the propellers and side thrusters. In this paper, three degrees of

freedom equations of the motions of crabbing are derived. The equations are used to apply the adaptive backstepping

control method to the auto-berthing controller of a cruise ship. The controller is capable of handling the system nonlinearity and uncertainty of the berthing process. A control allocation algorithm for a ship equipped with two propellers

and two side thrusters is also developed, the performance of which is validated by simulation of auto-berthing
