Title:
ANTI-GROUND EFFECT DISTURBANCE CONTROL METHOD AND DEVICE, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/061100
Kind Code:
A1
Abstract:
Disclosed in the present invention are an anti-ground effect disturbance control method and device, and a computer readable storage medium. The method comprises: enabling a preset anti-ground effect disturbance controller when a fixed-wing aircraft enters a landing pre-ballooning stage from a landing approach stage, otherwise, using a preset conventional controller (S1); using the anti-ground effect disturbance controller in a landing ballooning stage after the landing pre-ballooning stage, until the fixed-wing aircraft completes landing (S2); and enabling the conventional controller after the fixed-wing aircraft completes landing, until the flight is finished (S3). According to a full-automatic anti-ground effect disturbance control scheme, when the speed and height of the fixed-wing aircraft are reduced, the fixed-wing aircraft can be grounded more stably and smoothly by means of more efficient and accurate attitude correction, and the stability and safety of flight landing are improved to a great extent.
