Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0029] The present invention has designed a kind of ship track control method based on improved LOS guidance algorithm, such as figure 1 and 2 As shown, it includes the following steps:

[0030] Step 1: When the ship sails along a certain straight-line track segment of the predetermined track segment on the planned path generated by the set track point, the real-time actual track information of the ship is obtained by the ship's navigation module;

[0031] Step 2: Compare the real-time actual track information of the ship with the planned route, and when the real track deviation d between the real-time actual track information and the planned route of the ship exceeds the acceptable deviation d′, use the following method to run the improved The LOS guidance algorithm calculates the ship's expected course; otherwise, the ship's original planned...

Abstract

The invention relates to a ship track control method based on an improved LOS guidance algorithm. The method comprises the following steps: 1, obtaining the real-time navigation information of a ship by using the navigation module of the ship when the ship sails along a certain straight track segment in a path generated by set track points; 2, operating the improved LOS guidance algorithm to calculate a desired course when a track deviation between an actual track and a planned path exceeds an acceptable deviation d' or keeping an original planned track of the ship to sail if not; and 3, repeating the step 2 until the track deviation is within the acceptable deviation. The method applies the improved LOS guidance algorithm to the field of ship track tracking control, is clear in thinking and simple in algorithm, can control the ship to track the set ship course, is smooth in rudder angle change, and can avoid frequent steering of the ship.

Description

technical field [0001] The invention relates to the technical field of ship track control, in particular to a ship track control method based on an improved LOS (Line-of-sight, guidance algorithm) guidance algorithm. Background technique [0002] Water is an important part of the earth's homeland, and it is also an important resource for society to achieve sustainable development. As a means of transportation in water bodies, ships play an important role in national defense, national economy and ocean development. The ship has the advantages of stealth, intelligence, and does not involve the personal safety of on-site operators. Nowadays, as a hardware platform, ships are used in all aspects of civil and military applications. In recent years, the research and development of ships in the industry have emerged in an endless stream. Ships integrate technologies such as ships, communications, automation, robot control, remote monitoring, and networked systems, and realize fu...
