Embodiment Construction

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0059] figure 1 It is a schematic diagram of ship heading control in the prior art, which includes steps: the driver sets the ship heading SP of a certain voyage through the ship heading setting module, that is, sets the heading of the ship; , the ship heading PV deviates from the set ship course SP, e 1 ≠0 and e 1 >Δ (Δ is the dead zone and insensitive zone), the steering gear will act, adjust the deflection of the rudder blade accordingly, and generate an ...

Abstract

The invention provides a ship navigation control online self-adaptive adjustment method, which comprises the following steps: S1, setting an ideal ship route, if no wind wave flow disturbance force dominant direction exists, taking the ship bow direction as the ship navigation control direction, and otherwise, entering the step S2; S2, measuring the magnitude and vector direction of the wind waveflow disturbance force in real time, and setting an output value of a ship main engine and an included angle between the ship heading and an ideal ship route, wherein the vector direction of the resultant force of the propeller thrust and the wind wave flow disturbance force is the direction from the current ship centroid to the nearest reference point; S3, adjusting the included angle between theship heading and the ideal ship route and / or the output value of the ship main engine, and achieving interaction of the vector direction of the resultant force with the ideal ship route, wherein theincluded angle is smaller than a set threshold value; and S4, adaptively controlling a ship steering engine according to the acquired course deviation value, keeping the ship deviated from the coursewithin an allowable range, and repeating the steps S3 and S4. The invention further provides a ship navigation control online self-adaptive adjustment system.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to an online self-adaptive adjustment system and method for ship navigation control. Background technique [0002] Currently, the direction of oceangoing navigation of ships is achieved by controlling the heading of the ship. In the existing technology, the heading of the ship must be the direction of the ship, which requires frequent adjustments of the autopilot to overcome the interference of the ocean environment, making it difficult to keep the rudder blades in the neutral position. Even so, the driver needs to correct the course regularly. Solve the yaw, so the track route of the ocean-going ship is "Z" or "S" shape, and the additional resistance generated by the rudder effect affects the speed. [0003] The automatic rudder of an ocean-going ship is the key equipment for course keeping. The automatic rudder takes the deviation of the ship's heading from the set course as t...
