Abstract

The invention discloses a path tracking control method, system, storage medium and terminal of an unmanned boat, wherein the path tracking control method of an unmanned boat includes the following steps: creating a relative velocity motion mathematical model of the unmanned boat in a state of ocean current interference Model; Generate the position tracking error of the unmanned ship based on the mathematical model and the principle of virtual point tracking; Create an adaptive line of sight law guidance law based on the mathematical model and the principle of line of sight; According to the position tracking error and the guidance The law guides the unmanned vehicle to track the desired path. The path tracking control method, system, storage medium and terminal provided by the invention have high path tracking accuracy and can track curved paths.

Description

Unmanned boat path tracking control method, system, storage medium and terminal technical field The present invention relates to unmanned boat navigation control technical field, relate in particular to a kind of unmanned boat path tracking control method, system, storage medium and terminal. Background technique [0002] Unmanned surface vessel (USV) is widely used in marine production activities, In particular, it has outstanding advantages in marine resources survey, water quality monitoring and sampling, and sanitation. Unmanned sailing in the ocean Boats are often disturbed by environmental forces such as ocean currents, which will have a great impact on the path tracking control accuracy of unmanned boats. However, the existing path tracking control schemes of unmanned boats do not consider the current environmental force on the path tracking control of unmanned boats. It is difficult to directly track and control the arbitrary curve path of the unmanned vehic...
