Embodiment Construction

[0026] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0027] In order to facilitate the understanding, the related knowledge of multi-navigation state steady speed control of the ship is firstly introduced.

[0028] 1) The high-speed craft has an unstable speed range in the transition state.

[0029] The multi-navigation state refers to a ship (especially a high-speed boat), and its navigation process is divided into three navigation s...

Abstract

This application is applicable to the technical field of boat control, and provides a multi-navigation-state steady-speed control method and device for boats. The method includes: obtaining the current desired speed of the boat; Determine the target curve, and various resistance-speed curves are obtained by learning the controllable parameters of various drag-increasing and drag-reducing accessories. In the target curve, the expected speed belongs to the approximate linear controllable interval in the target curve; according to the target curve, determine The target parameter combination of various drag increasing and reducing accessories; according to the target parameter combination, the controllable parameters of various increasing and reducing drag accessories are adjusted to realize the resistance parameters of the target curve, so as to control the desired speed on the approximate linear control of the target curve. In the control interval; collect the current speed of the boat in real time, and calculate the speed deviation between the current speed and the expected speed; in the approximate linear controllable area of ​​the target curve, adjust the target thrust according to the speed deviation to achieve the closed-loop control of the expected speed.

Description

technical field [0001] The present application belongs to the technical field of boat control, and in particular relates to a multi-navigation-state steady-speed control method and device for a boat. Background technique [0002] Usually, when a ship is performing tasks such as surveying and mapping or tracking and interception, it needs to keep sailing at a certain desired speed value, that is, the ship has a need for steady speed control of the desired speed. The existing motion control technology is mainly to control the track from the course deviation and the position deviation control, so as to realize the speed control of the ship. However, when the ship is in a transitional state, due to the small or nonlinear curvature of the resistance-speed curve, it is difficult to achieve stable control of the speed in the transitional speed range. Contents of the invention [0003] In view of this, the embodiments of the present application provide a multi-navigation state st...
