国外无人机自主飞行控制研究

无人机自主飞行控制的研究属于飞行控制的前沿问题,其目的是实现无人机的自主飞行控制、决策和管理。由于其高度的复杂性和智能性,在理论和工程实际上尚处于起步阶段。结合近年来国外的发展状况和一些主要的研究成果,对无人机的自主飞行控制的研究进行了概述。首先介绍了自主控制的概念,然后分别探讨了无人机自主飞行控制中几个相关的关键问题,主要包括飞行中规划与重规划,自主飞行控制的分层结构,以及无人机自主着陆等问题,最后对未来的发展方向和面临的挑战进行了展望。

Survey of foreign researches on autonomous flight control for unmanned aerial vehicles

The study on autonomous flight control of unmanned aerial vehicles(UAVs)is a frontier problem of flight control. Its goal is to realize the autonomous flight control, decision making and management for UAVs. Because of its huge complexity and high intelligence, it is still in the early stage. The foreign researches and their results in this field are overviewed. In the first place, the concept of autonomous control is introduced. Then several related key issues are discussed respectively, including the in-flight planning and re-planning problems, the hierarchical structure of control systems, and the autonomous landing of UAVs. Finally, the researh areas are proposed to address development tendency and challenges.
