Fixed-wing unmanned aerial vehicle rolling maneuvering control method

Abstract

The invention provides a fixed-wing unmanned aerial vehicle rolling maneuvering control method. The method is applied to a fixed-wing unmanned aerial vehicle and provides an automatic control method for each control channel in the rolling maneuvering process. According to the method, 360-degree full-gesture seamless navigation is realized through a full-gesture combined navigation method; autonomous switching of the fixed-wing unmanned aerial vehicle between the upright flight state and the inverted flight state is realized through a rolling control method, and balance is rapidly established;and gravity potential energy is reasonably applied through a pitching rolling control method, safe and effective pitching rolling is realized, the flight direction of the unmanned aerial vehicle can be quickly changed under the condition that the safe angle of attack is guaranteed, and the unmanned aerial vehicle can be quickly separated from the dangerous situation in air combat. According to themethod, reasonable automatic control can be conducted on an engine and a control surface, flexible rolling maneuvering of the fixed-wing unmanned aerial vehicle can be realized, so that the unmannedaerial vehicle can freely switch between upright flying and inverted flying, and the flying direction can be quickly changed.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a field of simulating a fast maneuvering moving target by using a fixed-wing unmanned aerial vehicle, and belongs to the technical fields of unmanned aerial vehicles, autonomous navigation and flight control. Background technique [0002] The unmanned target drone is an important means of testing and identification of aviation weapon systems, and it is also an important support system for my country's actual combat military construction. Without a high-performance target drone, there will be no high-performance aviation weapon system. The U.S. Air Force launched the 5GAT fifth-generation stealth target aircraft project at a huge expense, providing a full-scale target aircraft that can simulate the real radar and infrared signal characteristics of stealth fighters for live ammunition shooting training and weapon testing. With the international service of stealth fighter je...

AI Technical Summary

Problems solved by technology

However, the existing main high-speed unmanned target drones in my country lack the ability to simulate fast maneuvering targets, and cannot flexibly switch between forward and inverted flight states, let alone achieve fully autonomous rapid rollover maneuvers. Therefore, research The rolling maneuver control method of fixed-wing unmanned aerial vehicles has very urgent needs and important significance
