Design and Experimental Analysis of Hardware and Software of Quadrotor Aircraft System

Quadrotor aircraft can lift vertically, widely used in the military and civil fields, in the design of aircraft, combined with single-chip design, can improve the overall performance. Therefore, the STM32F427 chip was used as the processor to design the aircraft system, build the four-rotor aircraft platform, and use the platform to carry out hovering and flight motion experiments on the control system and attitude estimation algorithm. The experimental results show that the control system and attitude estimation algorithm can ensure the hovering and stable flight of the aircraft, which has certain theoretical significance and engineering value.
