Ship track control method based on improved LOS guidance algorithm

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...
