Automatic course control system and method of rudderless ship

Abstract

The invention provides an automatic course control system of a rudderless ship. The automatic course control system comprises a GPS compass, a ship control apparatus, a propeller propulsion device and a rotation speed sensor. The ship control apparatus comprises a man-machine operation interface. The propeller propulsion device comprises a left propeller and a right propeller which are symmetrically installed at the stern, an engine and an engine controller. A current navigation speed and a current navigation angle measured by the GPS compass are computed with a target navigation speed and a target navigation angle which are input into the man-machine operation interface respectively and thus a target control rotation speed is obtained. The ship control apparatus carries out operation on an actual rotation speed of the propeller measured by the rotation speed sensor and the target control rotation speed, and the engine controller controls the engine to adjust the rotation speed square difference of the propeller. The invention further relates to an automatic course control method of the rudderless ship. The beneficial effects of the automatic course control system and method of the rudderless ship are that the system is simple in structure, technical requirement is low, cost is low, and the system and the method are easy to popularize and apply.

Description

technical field [0001] The invention relates to the field of ships, in particular to an automatic course control system and method for a rudderless ship. Background technique [0002] Ships generally use steering gear to adjust the course, and control the speed with the aid of propeller or jet propulsion systems, which are the core components of ship control. The basis for problems such as trajectory tracking, dynamic positioning, and automatic collision avoidance. Compared with the jet propulsion system, the propeller propulsion system has the characteristics of high power and low cost, and has been widely used for a long time. When the ship has a certain speed, the steering gear and its steering system achieve the effect of controlling the course by changing the swing state of the rudder blade. When the steering gear is used for steering, the turning radius of the ship is large, the course adjustment time is longer, and the resistance of the ship increases. [0003] In ...
