Design Of UAV's Flight Control Computer Based On ARM Processor

In this thesis, the design of UAV's flight control computer which based on ARM processor is deeply discussed. As a rising high tech furnishment, due to its unique advantages, UAV will play a more important role in modern informational battlefield. The embedded processor's application which is represented by ARM, has become a hot research field in embedded system. UAV's Flight Control Computer is a core component of the flight control system; determine to a large extent the level of UAV control system's performance and the UAV technology. Adopting the new generation of embedded processor as the core to design UAV's Flight Control Computer, may solve the performance and cost of these two indicators of the concept of mutual restraint, and achieve the match between them.In the thesis, the application of embedded control system based on ARM processor in UAV's flight control is introduced. The embedded processor S3C44B0X which practiced by applications is selected as the computer's CPU. After the selection, the computer's hardware is constructed through the memory's extension and the realization of data collection and communication functions. Then according to the flight control's application requirements, we design the operating system which meeting the real-time ability and corresponding software, then describe the composition and functions of the software. We transplant RTOS uC/OS-2 to FCC's hardware platform. Using data collection function's software realization as example, we introduce the FCC's software's development and debugging under ARM's environment. At the end of the papers, the design is analyzed and summarized, and the recommendations on improving and upgrading are put forward.
