Stability control of small fixed-wing UAV

The stability control of unmanned aerial vehicle (UAV) is the most important technology when it is on the duty of taking area photos. This paper aims at analyzing the structures, the corresponding channel of control and control modes in small fixed-wing UAV, and focuses on flight control system, which systematically reveals the running rules of UAV. According to the control theories in UVA, the paper explains the method of stability controlling UAV from two major aspects, the longitudinal and lateral movement control, based on the UAV flight operation process. By understanding the structures, the modes, the rules and the theories, the paper achieves the goal that can catch the method of fully controlling UAV.
