| Quadrotor UAV is a kind of micro-small helicopter and it has many good performances of VTOL (vertical takeoff and landing). This kind of helicopter can be widely used for military reconnaissance, aerial, search, emergency rescue, information access and the others.It can also perform different electron tasks, so it has good actual utility and development prospect. Now it has already gradually applied to national defense, civil, commercial and other aspects. It will be one of the most important development directions in the area of Quadrotor UAV for its research.For the aim to achieve the goal how to control the flight attitude accurately, This article has analyzed the present situation of flight attitude research, the key technologies and the foundation of application prospect of Quadrotor UAV, and conducts the research to its flight attitude technology, even according to the entire flight attitude control request about this system, making designment,improvement to it's hardware and algorithm.In the part of algorithm,my article not only uses DSP to realize designment of its controller,but also is a new attempt. to put the Quadrotor UAV hardware into practice.In the basic of the characteristics about DSP controller like control precisionthe high and response speed quickly, it provides a better kind of hardware to realize the aim to control the Quadrotor UAV flight attitude. In the paper research content, the writer first establish the mathematical model, then put forward two kinds of algorithm,one is for surveing it's high degree,the other one is for surveing it,s attitude to realizes Quadrotor UAV flight attitude control accurately. In other words,the information of this system of transmission machine mix the part of Quadrotor UAV control provides a practical and feasible way for the control of the Quadrotor UAV attitude. |
