An investigation of the Control Quality of the Automatic Control System for Fixed-wing UAVs During Landing Process

This study presents an investigation and evaluation of the control quality automatic system for UAVs in vertical plane under windy conditions. For operational stages general, landing stage is one high-probability that pose a threat to flight safety, especially at time landing. Therefore, evaluate system, authors investigated parameters during UAV The uses PID controller with optimal selected by Signal Constraint tool Matlab Simulink. predetermined wind model was used verify most extreme times. programs proposed paper are simulated on Simulink software.
