Abstract

The invention discloses a power positioning system and method for an unmanned ship. The system comprises a sensor measurement system, a control system and a power and propulsion system. The method comprises steps as follows: a hydrodynamic model of the unmanned ship under the action of multiple factors is established, and standard description of control of the unmanned ship is realized; the ship movement position and course are measured by various sensors installed on the unmanned ship, complicated real-time computing is performed by a computer, a multi-vector thrust control technology is used for decoupling control of the power positioning system, the purpose of cooperative control of thrust, rotating speeds and pitch angle is achieved, a thrust device of the unmanned ship is further controlled to produce propulsion force and torque to resist disturbing force caused by the outside environment, and the target ship position and ship heading of the unmanned ship are kept.

Description

technical field [0001] The invention relates to a method and system for dynamic positioning of an unmanned ship, in particular to a method and system for dynamic positioning of an unmanned ship based on intelligent control. Background technique [0002] With the implementation of my country's innovation-driven development strategy, unmanned ship technologies such as surface unmanned transportation vehicles, surface unmanned monitoring systems, and surface unmanned operation platforms have been temporarily driven by the Internet of Things, big data, cloud computing, and artificial intelligence. The field of unmanned ships has become the next blue ocean of industry, with broad research and application space. [0003] Unmanned ships will encounter external environment interference such as wind, waves and currents when navigating on the ocean. If the unmanned ship is to maintain a certain position with a certain reference line on the sea surface, the ship must have the ability to...
