英文摘要：

According to the dynamic changes of landing target difficult to accurately estimate, an autonomous landing algorithm was designed based on a new coordinate system with dynamic change. The new coordinate system changed dynamically with the trajectory of unmanned aerial vehicle（UAV） in the capturing phase, and changed with the ideal landing area in the tracking phase. The UAV＇s speed and position errors were calculated in the new coordinate system, the errors were corrected through the trajectory controller, and UAV accurate guidance was realized. An active service carrier UAV was regarded as the research object, the simulation system was constructed, and the flight control system was designed. Finally, the trajectory control parameter was optimized. Air wake and navigation error were added to verify and evaluate the performance of landing. The results show that this system can effectively guide the UAV to safely landing,and the landing performances can meet the design target.
