The Development Of Flight Control System And Flight Test Of Certain MAV

The thesis is derived from a basic research program.The research is about the flight control and relative technology for certain MAV.This paper focus on the design of flight control system, including flight control law and flight control software, and flight test.The paper firstly generalizes the character and application of MAV, then introduces the MAV's advancement and developing trend.The MAV's non-linear model is build based on the wind tunnel test data. The linear model is developed on the MAV's trim point. The flight control law, including attitude control, velocity control and height control is introduced. Because of the limitation of the linear simulation, the simulation based on the nonlinear model is also carried out. The disturbance of the airflow and the time delay for the MAV's flight status imformation are researched among these simulations.The navigation algorithm is designed in the paper, and the simulation is carried out.The flight control software is introduced, focus on the structure and function. And, experience from hundreds times of flight test is summarized, and the progress of adjusting control parameter, the realiziation of autonomous navigation in flight test is introduced. Some flight test result is given at last.
