Dynamic positioning simulation test platform and position control method

Abstract

The invention provides a dynamic positioning simulation test platform and a position control method. The dynamic positioning simulation test platform comprises a ship motion simulation computer (7), a three degree-of-freedom horizontal motion platform (8), a four degree-of-freedom motion rotary table (9), a data processing computer (4), a comprehensive display and control computer (6), a compass (1), a global position system (GPS) (2), and a mobile radio unit (MRU) (3), wherein the data processing computer (4), the ship motion simulation computer (7), the three degree-of-freedom horizontal motion platform (8), and the four degree-of-freedom motion rotary table (9) are connected to form a local area network through Ethernet, the four degree-of-freedom motion rotary table (9) is installed on the three degree-of-freedom horizontal motion platform (8), the compass (1), the GPS (2), and the MRU (3) are all installed on the four degree-of-freedom motion rotary table (9) and are connected with the data processing computer (4) through serial interfaces, and a data fusion algorithm (5) is loaded in the data processing computer (4). The dynamic positioning simulation test platform and the position control method can be used for simulating six degree-of-freedom motion of ships.

Description

technical field [0001] The invention relates to a dynamic positioning simulation test platform, and also relates to a dynamic positioning simulation position control method. Background technique [0002] With the increasing tension of land resources, all countries have shifted the center of economic development to the resource-rich ocean. In the 21st century, mankind has entered the era of marine economy, and the scope of human development and exploration of the ocean has become wider and wider. Dynamic positioning technology has played an increasingly important role in ocean drilling ships, deep-sea rescue boats, scientific research ships, and cable-laying ships. important role. In recent years, with the development of automatic control theory, the performance of dynamic positioning system has been continuously improved. [0003] The patent document with the publication number CN102074144A discloses a ship position motion test platform, which is composed of upper and lowe...

AI Technical Summary

Problems solved by technology

[0003] The patent document with the publication number CN102074144A discloses a ship position motion test platform, which is composed of upper and lower layers, each layer is a two-dimensional motion device, and can better realize the position control of the ship, but the platform It is not six-degree-of-freedom, and cannot simulate the six-degree-of-freedom movement and control of the ship

The US patent document US10233389A1 discloses a dynamic positioning system, which can maintain the position and heading of the surface ship, and has good anti-interference ability, but the system can only realize the dynamic positioning function of three degrees of freedom

[0004] The commonality of the above technical solutions is that they are all designed for the three-degree-of-freedom motion system, and it is impossible to conduct simulation tests on ships with six-degree-of-freedom motion
