摘　　要：基于总能量控制的下滑波束导引系统可以在无人机自动着陆时实现飞行速度与飞行航迹的解耦控制,从而控制无人机沿下滑线精准下滑。在研究下滑波束导引系统与总能量控制理论基础上,搭建控制系统结构及选取合适控制参数,并在Matlab/Simulink中建立无人机仿真平台,对此控制系统进行仿真研究。仿真结果表明:在整个下滑着陆过程中,基于总能量控制的下滑波束导引系统可以在实现油门与升降舵联合控制速度与下滑航迹,控制无人机快速、准确地跟踪下滑线,完成精确定点着陆。The glide beam guidance system is designed based on total energy control theory. This designed control system can achieve decoupling control of flight speed and flight path in Unmanned Aerial Yehicle （ UAY） automatic landing,then UAY？s accurate glide path is achieved. In this paper,the structure of the control system and the selection of appropriate con-trol parameters are built on the basis of glide beam guidance system and total energ^^ control theor^^. An UAY？s platfor^n is es-tablished in Matlab/simulink to simulate the control system. The simulation results show that the control system can achieve the combined control of the throttle and the elevator,which can decouple flight speed and flight path angle. Using this control system,the UAY can realize precise fixed point landing.
