Abstract

The invention discloses a method for acquiring the moving body bank to turn (BTT) turning control attitude information and a device for realizing the method, which belong to the fields of moving body dynamics, control and navigation. A moving body navigates in the water environment at the navigation speed of over 100m / s; and the method for acquiring the moving body BTT turning control attitude information comprises the steps of: firstly, extracting the movement attitude information of the moving body; then, acquiring the moving body BTT turning control attitude information, through decoupling and classifying the moving body BTT turning control attitude information, decomposing the BTT control information into the rolling channel attitude information and the pitching-yawing channel attitude information; and respectively estimating the hydrodynamic coefficients in the rolling channel attitude information and the pitching-yawing channel attitude information, and obtaining the complete moving body BTT turning control attitude information. The method can be used for enabling the moving body to stably turn at the navigation speed of over 100m / s in the water navigation environment, so an air curtain which wraps the moving body is kept stable.

Description

technical field

[0001] The invention relates to a method for acquiring BTT turning control attitude information of a moving body, which is particularly suitable for turning control of a high-speed moving body navigating in an underwater environment, and belongs to the field of moving body dynamics, control and navigation. Background technique

[0002] At present, the research on the control of moving bodies navigating in the underwater environment is mainly aimed at the longitudinal motion. Scholars have proposed various controller design methods and achieved some results. For the control of the lateral motion of this type of moving body, referring to the lateral motion control and turning control of the aircraft, there are mainly two strategies, namely the traditional sideslip and turn (STT) control technology and bank turn (BTT) control technology. .

[0003] Most aircraft in the world adopt STT turning control technology. This control technology keeps the longitudinal ax...
