摘　　要：本文以工程实践为背景,针对某对象无人机空中发动机停车情况下的着陆过程,提出了在纵向通道内使用"变轨迹角控制"的思想,用以确保纵向通道内无人机以合适的飞行速度跟踪着陆轨迹。并以此为基础,设计了无动力情况下无人机着陆的纵向控制方案,克服了常规控制策略中升降舵无法同时实现跟踪高度和控制速度的缺点,并通过数字仿真验证了应急着陆中使用该控制策略的合理性。In this paper, we focus on the emergency landing after engine failure of unmanned aerial vehicle （UAV）. The principal problem in longitudinal channel during forced landing procedure is analyzed, and a kind of longitudinal control method, ＂path angle regulating control＂, which is designed for engineering application, is presented in this article. The path angle regulating control can make an outstanding performance in both path tracking and velocity control by using elevator only. The simulation results show the suitability of the control method during emergency landing.
