Design and Implementation of Rotary Unmanned Aerial Vehicle Onboard Flight Control System with 3G-WiFi Dual Linkage Performance

摘要

The objective of this research is to develop a real-time embedded onboard flight control system (FCS) that provides dual communication linkage functionality and real-time signal processing for a pilot command, guidance, navigation, and control of a rotary unmanned aerial vehicle (UAV) system. In particular, dual communication linkage is realized through wireless LAN and high speed packet access (HSPA) channel. A virtual instrumentation platform and hardware is employed for the design and implementation of the embedded algorithms. All the low level data processing and algorithms coding are realized through graphical system design software. Installed with the dual communication linkage and FCS with auto pilot capability, the rotary UAV flight test is done. The flight test results demonstrated a meter level navigation accuracy compared with the pre-defined waypoint trajectory, with seamless data communication between ground station and onboard FCS.
