UAV Gust Wind Mitigation Measurement and Control System Design

Abstract

UAVs are susceptible to turbulence when flying, which can alter the expected navigational attitude, flight trajectory and other states and affect the reasonable execution of the mission, and gust mitigation technology is a powerful means for UAVs to cope with the effects of gusts. This paper designs a gust mitigation measurement and control system for UAVs using the STM32H743 as the control core. The system consists of a master control unit, a data acquisition module, a serial module, a rudder control module and a data storage module. When the UAV is affected by gusts of wind, the system acquires the current flight status of the UAV by accurately collecting data from the UAV sensors, and then combines the control commands from the ground station and the flight control to fuse and solve the data, and then generates rudder control commands to control the rudder deflection, so that the UAV can maintain stable flight and achieve gust mitigation. After actual circuit fabrication and experimental testing, the measurement and control system designed in this paper can achieve stable serial communication, accurate analogue signal acquisition, precise motor and rudder control and stable power supply, meeting all the indicators and requirements required to achieve gust mitigation.
