Design and Implementation of a UAV Drone Stall Automatic Recovery Method
To address the safety issues of UAV caused by drone flight stall,this paper develops an automatic recovery mechanism at critical stall.The flight control computer compares the data difference with the left boundary,triggers stall protection below the safe speed,locks the current altitude,adjusts the engine gear cumulative speed,and continues to fly along the preset route when the speed meets the requirements.This method enables the drone to have autonomous de-cision-making and automatic recovery functions,It greatly improves the safety of drone flight and has important engineering value.
