Finely segmented parafoil homing control method

Abstract

The invention relates to a finely segmented parafoil homing control method which comprises the following steps: S1, acquiring navigation parameters of the parafoil through a navigation module, wherein the navigation parameters comprise position, height, speed and flight direction of the parafoil and a yaw angle of a target center; S2, performing data analysis on the acquired parameters through the navigation module, and outputting effective data to a parafoil control module; and S3, performing comprehensive analysis and discrimination on the navigation data through the parafoil control module, and transmitting a control signal according to a fine segmentation method. The segmented homing method is subjected to fine segmentation, a homing path of a low-altitude parafoil is reasonably planned in an emphasized mode according to real-time height, position and other information of air-drop system, a corresponding control strategy is formulated, an adverse effect of low-altitude air and other environmental factors on the control precision of the system is reduced, an autonomous homing path of the parafoil is effectively controlled, landing precision is controlled in an effective range, and the landing precision is improved.

Description

Technical field [0001] The invention relates to the homing control field of parafoil, and more specifically, to a subdivision and segmented paraglider homing control method. Background technique [0002] At present, the segmented homing control of parafoil in the precision airdrop system is roughly divided into the centripetal section, the energy consumption section and the landing section. The centripetal section adopts the mode of centripetal flight, the energy consumption section circulates around the landing point; the landing section is adjusted to the upwind state for landing. This segmented mode is relatively rough, with simple manipulation strategies, and cannot adapt to the changing weather environment. Because the wind at low altitude has a greater impact on the landing accuracy of the system, coupled with the inherent time lag effect of the parafoil system in the precision airdrop system, it is difficult to accurately control its landing against the wind according to ...
