Abstract:

In this article, a flight control platform for small UAV based on ARM microprocessor and DSP chip is developed aiming at the problem of low processing speed and accuracy of traditional flight control platform using single processor. The architecture of the platform and solutions of the key technology are described. The GPS ground speed, airspeed, brake control volume, and feedback volume have been simulated by building the ground real-time simulation environment. The simulation results have proved that the speed and accuracy of flight control platform is improved greatly which can meet the requirement of system control and is pretty practical.
