碩士 / 國立成功大學 / 航空太空工程學系碩博士班 / 91 / Implementing UAV automatic navigation and autopilot system by using DSP, FPGA and GPS Modules are the major contributions of the paper. The main actions are as follows. UAV using GPS receiver gets present longitude and latitude position data from Global Position System. Then we use vector navigation calculation to correct UAV’s direction. After the direction is defined, FPGA will send PWM signals to drive servomotors. This action will change UAV’s control surfaces and let UAV reach to target position. When developing the DSP project, we employ Simulink and RTW（Real-Time Workshop）as design tools to make DSP implement easily.
The auto navigation system of UAV has been proved well-done via several experiments, and we found that the navigation control law is also correct and match up with the designing logic. In face of the problem of control surfaces, not only the resolution of motors’ rotation becomes higher, but also the three control surfaces of UAV can be controlled by FPGA at the same time. In the face of communication, GPRS module is used as a medium of transfer, and makes the functions of UAV more perfect.
