Abstract:In order to keep the tracking results of pitch angle, roll angle and yaw angle consistent with the actual trajectory of unmanned aerial vehicle (UAV), and realize the accurate tracking and control of the whole trajectory, a tracking control system of UAV trajectory based on Beidou communication technology is designed. According to the application standard of Beidou communication technology, three protocol files with different formats are defined: operation and maintenance message, notification and negotiation message and business data message. Based on this, the internal structure of UAV is deeply analyzed, and then the dynamic modeling of UAV trajectory tracking control system is completed by combining with a large amount of traveling attitude data. Ensure the smooth connection of the main supply circuit, match all the transmitted power to four types of hardware application structures: full-drive motion structure, attitude regulator, adaptive controller and trajectory tracker, complete the design of the main control structure of the system, and combine all the software and hardware operating conditions to realize the design of the trajectory tracking control system of UAV based on Beidou communication technology. According to the experimental results, under the influence of Beidou communication technology, the tracking results of pitch angle, roll angle and yaw angle obtained by the system host will not be significantly different from the actual trajectory of the UAV, which is more in line with the application requirements of accurately tracking the complete trajectory of the UAV compared with the application system based on adaptive integral backstepping method.
