Abstract: This paper analyzes and researches the principles and key technologies of the modules of the more advanced UAV flight control systems at home and abroad. The sensor drive module, navigation control module, flight control module, and Avalon bus control module are designed using Verilog HDL language. The navigation control IP core and flight control IP core were constructed using Altera's most advanced SOPC integrated development tool Qsys. Finally, a UAV flight control system with navigation and control dual IP cores as the core was designed and implemented. The dual IP core UAV flight control system developed based on Qsys tools not only has fast instruction processing speed, occupies less hardware resources, but also has the advantages of high system integration, low cost, good robustness, and strong reconfiguration. UAV flight control systems built on traditional microcontrollers and ordinary DSP chips have certain application value and practical significance.
